双频双极化微带共形天线

设计了一款工作在不同频率的双极化微带共形天线。首先,天线单元采用矩形微带贴片,并且通过改变贴片尺寸实现两种谐振频率;其次,改变两种单元的馈电方向,以此实现不同极化辐射;最后根据天线单元排布形式,设计了基于T 型功分器的馈电网络。根据最终的仿真结果,加工了天线实验样机。在工作带宽内,天线1、2 不圆度为分别为3. 56dB 和3. 98dB,增益分别为1.1dBi 和0.85dBi。通过比对,实测结果与仿真结果一致性较好,达到了预期目标。

Dual-Band Dual-Polarization Microstrip Conformal Antenna

This paper presents a novel dual-band dual-polarization microstrip conformal antenna. First, the conformal antenna is composed of the rectangular microstrip patch unit. And the dual-band is achieved by changing the patch size. Secondly, the different radiation polarization is realized by changing the feed direction of the unit. Finally, according to the antenna unit arrangement form, we design of the feed network which based on the T shape power divider. The pattern roundness of antenna 1 and 2 is 3.56dB and 3.98dB, respectively. The gains are 1.1dBi and 0.85dBi, respectively. Both experimental and simulated results show that a good agreement with simulation results.
