Dual Segment Dielectric Resonator Antenna for Microwave Applications

Abstract

This paper presents, a dual-segmented Rectangular dielectric resonator antenna (RDRA) fed by a modified conformal strip for wideband application is proposed. $TE_{1,\delta,1}^{y}$ and $TE_{1,4,1}^{y}$ modes have been excited which show well-balanced radiation pattern and decent radiation efficiency throughout the bandwidth. The proposed antenna geometry is wideband in nature i.e. 4.32-7.27 GHz. Simulated gain of 7.04 dB was observed at 4.88 GHz while 5.46 dB was observed at 6.66 GHz. It can be concluded that the presented antenna is suitable for WLAN application (5. 15-5.835 GHz), Amateur Satellite (5.6 GHz), Microwave radiometry and various applications in 4-7 GHz frequency band.
