Compact Dielectric Annular Grating Antenna for Millimeter-Wave Applications

This paper reviews a simple and compact dielectric annular grating antenna. The proposed antenna made of high resistivity silicon using silicon platform. The antenna is fed through Dielectric image guide (DIG), with a maximum gain of 18 dB, and wide bandwidth more than 7 GHz which is suitable for commercial applications, such as mobile radio, short range wireless communication and W-band applic...

Bandwidth Enhancement Techniques of Dielectric Resonator Antenna

The paper briefly reviews the historical background of dielectric resonator antenna and its bandwidth enhancement techniques. The main focus is on a compact DRA that can offer broad band operation. It has been illustrated that dual resonance and multi resonance operation can be much effective to give wide band characteristics of DRA. Index Terms dielectric resonator antenna, broadband, multi re...

A Millimeter-Wave Wideband High-Gain Antenna Based on the Fabry-Perot Resonator Antenna Concept

A compact millimeter-wave (MMW) wideband high-gain antenna is proposed and implemented. The development is based on the design principle of wideband Fabry-Perot resonator antennas (FPRAs). The antenna consists of triple-layer dielectric slabs and a PEC ground, and it is fed by a rectangular waveguide. All slabs are used to form the superstrate that exhibits the increasing reflection phase at th...
