Abstract
In this paper, an asymmetric coplanar strip (ACS) fed microstrip antenna is proposed, which is matched by an active circuit to increase the bandwidth. The proposed antenna is composed of feeding line, asymmetric ground plane, rectangle radiation patch. The antenna operates at 384 MHz and 645 MHz with a small fractional bandwidth of 19.2% and 18%, respectively, when the active circuit is not incorporated into the antenna matching network. By properly designing and optimizing the active circuit, the bandwidth has been greatly enhanced and a −10 dB fractional bandwidth of 197.7% from 5 MHz to 877 MHz has been achieved for the proposed antenna system.
