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 applications in Millimeter Applications requiring high Gain, efficiency, data rate, and large bandwidth. The main features of the proposed antenna that is achieved by designing low-cost, compact size, and ease of fabrication and integration. The simulation gain of the antenna is 18 dB at 102 GHz with radiation efficiency better than 95%.
