A wearable microwave head imaging is proposed for medical applications, namely stroke and cancer detection. The wearable device in a hat-like structure incorporates an array of flexible ultra-wideband antenna. The antenna array consists of 8 monopole antenna elements which act as multi-static radar. A lossy dielectric absorber is embedded inside the hat to improve the directivity of the antenna. The antenna operates in the frequency range of 1.5GHz to 4GHz which would provide sufficient penetration and resolution for the proposed head imaging system. A thin and flexible FR-4 of thickness 0.2mm is used as the substrate of the antenna. The performance of the antennae when arranged in a hat like shape structure was measured and analysed. The return loss of the antennae shows a match across all the operating frequency range. The average simulated gain of the antenna is 3 dBi. © 2016 EuMA.

Smart Antenna Technologies | Date: 2016-12-01

The invention relates to a balanced antenna system comprising a radiator connected via a matching circuit to a balun. In certain embodiments, the radiator comprises a first radiating element and a second radiating element and the matching circuit comprises a first impedance-matching circuit connected to the first radiating element and a second impedance-matching circuit connected to the second radiating element. The first and second matching circuits may be identical and are connected through the balun to a single port. To minimise the component count, the design of the matching circuit and balun is co-optimised.

The scan range of an antenna array can be increased by providing a degree of curvature to its structure. However, achieving a wide scan range with an antenna array with limited number of elements is a challenging design issue. In this study, a novel 8-element linear array of polarisation reconfigurable antennas conformed to four different array structures; namely 2-faceted, 3-faceted, 4-faceted and 8-faceted are analysed and synthesised. Observations are made on the influence of the tilting angle of the faceted structures to the geometrical characteristics and the scan range of the array. It is shown that the 3-faceted array can achieve the widest scan range with the smallest dimension compared with the other faceted structures. Furthermore, the results show that the 3-faceted structure achieves ±69° compared to ±56° achieved with a linear array. © The Institution of Engineering and Technology 2012.

This paper presents a novel miniaturised microstrip-fed planar monopole antenna with Archimedean spiral slot to cover WiFi, Bluetooth and LTE standards. The base of the proposed antenna is a circular patch that operates in high frequency range, targeting compact circuit dimension. To create a multi-band antenna, Archimedean spiral slots, acting as resonance paths, have been integrated with the circular patch antenna. Analysis of the current distribution on the antenna reveals that at low frequencies the additional of the slots create new circular current paths, which form a wideband low-frequency response. Different shapes of Archimedean spiral slots have been investigated and compared. The miniaturised and optimised antenna exhibits a bandwidth of 2.2GHz to 2.9GHz to cover WiFi, Bluetooth (2.45GHz) and LTE (2.6GHz) mobile applications. The proposed antenna achieves low return loss, large gain, high efficiency and stable omnidirectional radiation pattern across all the relevant bands. The antenna is implemented and fabricated on an FR4 substrate. Reflection coefficient measurement results closely correlate with those obtained during design simulations. The presented antenna can be particularly applied to commercial multiband communication systems. © 2013 IEEE.

In this paper, a single Ultra-wide Band (UWB) antenna based microwave imaging system for breast cancer detection is presented. In contrast to other breast cancer detection systems such as multi-static radar, the system presented here is only based on a single Vivaldi antenna, to collect signals by scanning a cancerous breast phantom. These collected signals contain cancerous tissue information, which are then post-processed to create a microwave image of the breast, with the tumour highlighted. To gain insight into the performance of this microwave system, numerical experimental results are measured using a gelatin-oil technology based realistic cancerous breast phantom, with simulated results being compared to demonstrate the suitability of this microwave imaging system for breast cancer detection. © 2013 IEEE.

With a promising future for generation of electricity to power electronics, RF energy scavenging has become a matter of significant interest in recent years. In this paper, a small-size printed planar inverted-F antenna (PIFA) is designed dedicated for compact mobile RF energy scavenging system to extract power from ambient RF energy. The proposed PIFA has its working frequencies at about 900 MHz and 1800 MHz to form lower and upper band that cover GSM 900 and DCS 1800 respectively, yet it only occupies a small printed area of 20×40 mm2 on the system circuit board. Power around -15 dBm is received by proposed antenna at distance of 500m from base station which reveal reasonable performance for RF energy scavenging at moderate distance. © 2013 IEEE.

Smart Antenna Technologies (SAT at http://www.smartantennatech.com/ ) designs, develops and has patented new smart antenna technologies that offers both size and performance improvements, in excess of those obtained with conventional designs, at a reduced cost. The market for these products is huge (in 2015 over 359m laptops & tablets, and 1.91bn handsets, 235m smart TVs were sold, representing over 2.27bn devices globally, and this is expected to grow to over 2.5bn by 2020). SAT is currently working closely with one global laptop manufacturer (annual sales 45m units) on a non exclusive basis, with a prototype which is currently operational (TRL 7), and is now looking for the funding to conduct a feasibility study (Phase 1) to write a comprehensive business plan and presentation, to roll this out to a number of other laptop and tablet manufacturers, and potentially also smart phone applications as soon as possible for commercialisation via a licensing model. The objectives of the feasibility study is to more accurately assess the market potential of this new antenna systems and then prioritise it in terms of which sector to initially focus on (phones, laptops, TVs etc), what if any are the additional bespoke requirements of clients within each sector, and the relative timing to market, in addition to the financial/economic analysis (see below). SAT is looking to gain a firsthand understanding of the potential of specific customer demand, timetable, and any bespoke specifications they may have in order to determine the cost benefit analysis accurately, and ultimately the potential return on investment. With this information SAT will be in a strong position to write an accurate informed and focused business plan to raise further capital to exploit the market opportunities. The final objective is to have as many of the global mobile devices using SATs new more advanced, smaller antenna technology as possible.

Smart Antenna Technologies (“SAT”), a spin off from University of Birmingham in 2013, is researching and developing the next generation of smart multiband, multi-functional, multiport compact configurable antenna systems for laptops, tablets, smart phones, automotive applications and other mobile/portable devices. Thus, the aim of this project is to develop a bench Prototype Demonstrator (“PD”) to meet the current and future demands of the smart phone market. These patented new antenna systems reduce the number of antennas from several (typically seven in a modern smart phone) to just a single miniaturised antenna system, allowing WiFi, Bluetooth, 4G and GPS to all run concurrently (see appendix A), therefore considerably reducing costs, power usage, and materials, size/space used. In addition, it has significantly enhanced performance over existing antennas covering all frequencies between 400MHz and 6GHz and it also supports the new and emerging 4G Long Term Evolution (LTE) market increasing the phone life. There is substantial interest in the SAT technology and capabilities from some of the top OEMs in these markets, but while SAT is keen to exploit as many of these as it can, it does not have the resources to follow all these opportunities. SAT has considerable experience in fabrication a PD as it is currently working with a global laptop manufacturer and a global chip design/manufacturer developing a laptop antenna systems for them. With additional resources it could also be exploiting the considerably larger smart phone market while it has the technological lead over others. If successful, SAT would immediately employ 3 additional engineers, and by 2020 there should be at least an additional 20 to 25 new jobs created in SAT. It is anticipated that the project to make one PD for just one phone will require approximately £624k of funding in total and will last approximately 21 months from early 2016
