An antenna design is presented for antenna performance improvement for WLAN applications at 5.2 GHz and 5.8 GHz. Improved Patch antenna gain and radiation efficiency has been achieved in this work. Two CSSRR have been etched in the ground plane to achieve size reduction for dual band operation. The proposed antenna provides good flexibility on selection of(More)
In this paper the design of a Co-Planar waveguide (CPW) fed rectangular slot microstrip patch antenna is presented. This antenna is simulated in Microwave Studio on Computer Simulation Tools (CST 2012). In this design two H-slot have been etched on the ground in order to make wideband antenna. This slot on the ground helps in reducing the overall size of(More)
In this paper, Plasmonic based microstrip patch antenna has been proposed. The proposed antenna is suitable for WLAN, Wi-Max and DSRC applications. The antenna resonates at 5.9 GHz with Return Loss of -48.47 dB and gain of 7.6 dBi. By using the metal grating; Gain, VSWR, Return Loss have been improved as compared to the conventional microstrip patch antenna(More)
In this paper an experiment has been done on proposed algorithm for calculation of wall parameters. 2D-beam forming image has been developed by using calculated wall parameters, but calculated wall parameters are not so exact so auto focusing techniques based on higher order statistics has been presented that correct wall ambiguities. All data has been(More)
Presented here is a design of a UWB antenna with four notches. The notches are achieved using overlapped CSSRRs and ground resonators. The four notches are at frequencies 3.6GHz, 4.6GHZ, 5.0GHz and 5.8GHz, where these four frequencies fall in WiMAX, HiperLAN, HiperLAN and WiMAX bands respectively. The notches in the response are created by resonating(More)
This paper presents a brief overview of some hybrid techniques adapted for Peak to Average Power Ratio (PAPR) reduction. The (PAPR) reduction in Orthogonal Frequency Division Multiplexing (OFDM) system has received widespread attention from over the world during the last decade, leading to the successful development of several techniques for PAPR reduction.(More)
