Abstract

A MEMS (micro electro-mechanical- system) unidirectional radiation fractal microstrip antenna using coplanar coupled feeding method combining the ground with a particular shape of slot is proposed. The particular shape of ground-plane slot with the combination of coplanar coupled feeding method enhanced the bandwidth of antenna. The construction method of the shape of ground-plane slot is to copy the fractal shape of the upper antenna slot accordingly to the ground plane, and to simplify, transshape the shape of ground-plane slot. -10dB bandwidth of the proposed antenna element（70MHz） is a double of that of the conventional contact fed antenna without ground slots（30MHz）, at operating frequencies around 1.96GHz，and the gain reduction is only 0.18dB compared with the contact fed antenna without ground slot.(changed into 3.79dB from 3.97dB). -10dB bandwidth of 2 elements antenna array is about 100 MHz, at operating frequencies around 1.93 GHz, and the gain of the antenna array is about 6.3dB. So far as I know this is a novel bandwidth enhancement method.
