A hybrid power system may be used to reduce dependency on either conventional energy or renewable systems. This article deals with the sizing, generator running hours, sensitivity analysis, optimisation, and greenhouse gas emission analysis of hybrid renewable energy systems (HRES). Two locations have been selected where the feasibility of using different hybrid systems is studied for the same load demand. One site is the small remote community of Amini in the Lakshadweep Islands, located in southern India in the Arabian Sea, where solar and/or wind energy is always available throughout the year to provide energy security. Another place is the rural township of Hathras, in the northern Indian state of Uttar Pradesh, where agricultural biomass is found in abundance for the whole year. A comparative study has been made for the two locations for the same load demand by simulating HRES. To achieve the goal of simulation, the hybrid optimisation model for electric renewables (HOMER) software of the National Renewable Energy Laboratory, USA, is used. An optimisation model of a hybrid renewable system has been prepared which simplifies the task of evaluating the design of an off-grid/standalone system. After simulating all possible system equipment with their sizes, a list of many possible configurations may be evaluated and sorted by net present cost to compare the design options. An elaborate sensitivity analysis has been used for each input variable; the whole optimisation process is repeated to get simulated system configurations © 2009 Taylor & Francis.

One biomass energy source is rice husk, which is a very promising renewable energy source as it is an indigenous, cheap, and clean source of energy. However, environmental and financial profiles of electricity generation from rice husk must be assessed to ensure reduction in greenhouse gas (GHG) emission and positive cash flow. GHG emission from a rice husk generating system is significantly less than that from fossil fuel power plants. A dual-fuel diesel engine-generator of 800kW, using a rice husk gasifier, is considered for this analysis. This paper presents a comprehensive analysis of a traditional energy technology in a new perspective. The results of simulation data analysed in terms of pollution through GHG emissions, financial aspects, and suitability of the scheme for underdeveloped villages in economically developing nations are critical contributions of the paper. It also indicates the expected energy generation from the rice husk available in the region. © 2011 Taylor & Francis.

Metamaterial like EBG (Electromagnetic Band Gap) structures are used in slotted microstrip antenna and mobile handset applications for increasing efficiency and better return loss characteristics. As we know that traditional microstrip antennas have inferior feature in case of bandwidth. In this paper an antenna with slotted ground plane and patch has been developed in which EBG structure is used as a metamaterial above the ground plane for reducing surface wave losses. This antenna has desirable characteristics for use in mobile communications at two frequency bands (2067-2245 MHz) covering UMTS band and (2390-2795 MHz) covering ISM band whereas antenna using EBG structure is working at three frequency bands covering GSM, UMTS and ISM band. The patch size of this antenna is relatively small and is compatible with integrated circuits, and with EBG structures it covers three frequency bands. © 2011 IEEE.

The popularity of microstrip antennas are increasing day by day because of easy analysis and fabrication, and their attractive radiation characteristics microsrip antenna using simple electromagnetic band gap (EBG) substrate has higher gain than conventional microstrip antenna In this paper we propose to mushroom like Electromagnetic Band Gap (EBG) structure with different diameter of vias was designed to analyze the behavior of the EBG structure. Mushroom-like electromagnetic band-gap (EBG) structures exhibit unique electromagnetic properties that have led to a wide range of electromagnetic device applications and A simple, compact EBG microstrip antenna is proposed in this study that covers a wideband of 2.5 to 3.7 GHz ISM band, Bluetooth and UHF RFID applications. The use of the EBG Structure improves the radiation pattern of the antenna. The electromagnetic band gap structure is a periodic structure which exhibit a band gap over a certain frequency range over which the propagation of the electromagnetic wave is prohibited. Zeland IE3D simulations have been carried out to investigate and characteristics of the performance with improved design is under consideration in EBG Structure. © 2012 GIRI.

In this paper the analysis a new base station receiver is proposed and analyzed for a code-division multiple-access (CDMA) cellular system. The proposed receiver can achieve remarkable diversity gain by increasing diversity order with reasonable cost and complexity. From the numerical results, it is confirmed that the proposed receiver structure can be a practical solution for enhancing reverse-link capacity and improving performance in CDMA cellular system operations.

Annular slot antenna having dual port and dual band which is suitable for use in the feed-back path of an oscillator resulting in an active antenna configuration by using the modern MIC and MMIC fabrication technology, compact light weight, and low cost active antenna are realized. The proposed antenna is designed to radiate and transmit equal amounts of power. The return loss of the proposed antenna is higher than that desired for one-port antenna application at the desired dual-band frequencies. The antenna is fabricated on one side of a Neltec substrate (εr =3.3 and thickness = 0.762 mm) and the microstrip feeding line is fabricated on the opposite side of the board. The antenna was designed to operate at WLAN bands centered at 2.4 and 5.2GHz. The simulated and measured results show fairly good agreement. The measured return losses were found 20.5 dB at 2.4 GHz and 13.9 dB at 5.2GHz while simulated return losses were 9.36 dB at 2.4 GHz and 31.35 dB at 5.2 GHz. The radiation pattern is approximately omnidirectional at both frequencies in H-plane. © 2011 Global IT Research Inst.

In this paper we have described simulated as well as experimental results concerning miniaturization and enhanced performance of antennas using Metamaterials. One of the objectives is to obtain devices more compact and their enhanced performance than previous results. Antennas presented here using Metamaterials or Electromagnetic Band Gap (EBG) structures or Single Negative Structures (SNG) or Double Negative Structures (DNG) or Tunable Electromagnetic Band Gap Structures and Resonant Structures are more efficient than antennas without Metamaterials. We show that under proper conditions these materials are used for making Efficient, Miniaturized, Enhanced, Single band or Multiband Operating and Beam Steerable Antennas. © 2011 IEEE.

UWB technology- (operating in broad frequency range of 3.1-10.6GHz) based filter with WLAN notch has shown great achievement for high-speed wireless communications. To satisfy the UWB system requirements, a band pass filter with a broad pass band width, low insertion loss, and high stop-band suppression are needed. UWB filter with wireless local area network (WLAN) notch at 5.6GHz and 3dB fractional bandwidth of 109.5 using a microstrip structure is presented. Initially a two-transmission-pole UWB band pass filter in the frequency range 3.1-10.6GHz is achieved by designing a parallel-coupled microstrip line with defective ground plane structure using GML 1000 substrate with specifications: dielectric constant 3.2 and thickness 0.762mm at centre frequency 6.85GHz. In this structure a /4 open-circuited stub is introduced to achieve the notch at 5.6GHz to avoid the interference with WLAN frequency which lies in the desired UWB band. The design structure was simulated on electromagnetic circuit simulation software and fabricated by microwave integrated circuit technique. The measured VNA results show the close agreement with simulated results. Copyright © 2012 Harish Kumar and MD. Upadhayay.
