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

The implementation cost of a phased array antenna is high due to the large number of RF components required in the system. Migrating from the multiport beamforming system to a single-port beamforming system is a promising alternative. In this letter, a novel single-port beamforming algorithm using the pseudo-inverse function is proposed. The signal received at each element is estimated from the combined signal that is generated by the single-port output system. With the estimated values, the array weight is then calculated for the desired radiation pattern. The single-port concept is implemented on a 3-faceted antenna array and simulated in MATLAB. The results show that adaptive beamforming can be achieved with the estimated signals, and this technique has a faster execution time compared to a multiport beamformer. With reduced component count and implementation cost, the proposed technique demonstrates potential for commercial deployment in the mobile communication industry. © 2002-2011 IEEE. Source

Sensing capabilities of radio frequency identification (RFID) have recently been investigated both theoretically and experimentally. Frequency-modulated sensors utilize the modulation frequency for carrying sensor information when interrogated by a reader device. This paper derives analytical expressions for optimizing the electrical circuitry of such a sensor, as well as a figure of merit for selecting a suitable diode for rectification. A novel design strategy for optimizing an RFID sensor based on frequency modulation is presented, and it is used to design, fabricate, and experimentally characterize an optimized sensor. The result of this paper shows that a change in the sensor capacitance can be detected across a distance of 15 m with low uncertainty. © 2016 IEEE. Source

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. Source
