Cylindrical Dr Antenna Design

Dielectric resonator antennas (DRA) are attractive as alternative to patch antennas because of their small size and wideband bandwidth. This DRA is positioned over a feeding pad in a conducting ground plane in a way that excites the HEM mode. The DRA offer advantages such as low cost, ease of manufacture, wider bandwidth, and high radiation efficiency. This design presents an examination of DRA operated at C-band frequencies. A parametric study is performed to optimize the antenna performance and a prototype for microwave and WLAN application has been designed and measured.
