Abstract

This paper presents the design and development of a multi-element multi-segment half-sectored Cylindrical Dielectric Resonator Antenna (MEMSh-CDRA) with coaxial probe feed. The input and radiation characteristics of the proposed MEMS h-CDRA are investigated through the Ansoft HFSS simulation software. To validate the antenna performance, the proposed h-CDRA is fabricated and experimentally investigated. The simulation results are compared with measured data, and they are in good agreement with each other. The proposed MEMS h-CDRA is excited with coaxial probe feed, which excites TM_01δ dominant mode fields in the h-CDRA elements. The proposed MEMS h-CDRA provides wide bandwidth (≈ 120.3%) with gain of 6.45 dBi at resonant frequency (6.4 GHz). The measured gain is more than 4.0 dBi in entire operating frequency band (5.3 GHz-13.0 GHz) with monopole type radiation pattern. The bandwidth as well as gain enhancement is experimentally observed in the proposed structure. The proposed antenna has found suitable application for WLAN and WiMAX as well as X-band wireless applications.
