摘要

本文提出了一种非对称共面馈电微带天线，该天线与有源电路相匹配以增加带宽。该天线由馈线、非对称地平面、矩形辐射贴片组成。当有源电路未并入天线匹配网络时，天线工作在384 MHz和645 MHz，带宽分别为19.2%和18%。通过对有源电路的合理设计和优化，该天线系统的带宽得到了极大的提高，在5mhz ~ 877mhz范围内实现了- 10 dB的分数带宽，带宽为197.7%。

An ACS-fed Super Wideband Active Antenna

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.
