为了减少无线通信中的干扰，并满足多个无线通信系统实现多系统共用和收发共用，天线需在宽频带及不同频段下工作。分析并设计了一种性能优异的新型双频微带天线，采用电磁仿真软件HFSS 10.0对所设计的天线进行了仿真分析研究。仿真分析结果表明，该天线工作的频段分别为1.67~1.84 GHz和233~253 GHz，且天线的相对带宽分别达到9.71%和8.23%，天线可以作双频宽带天线，用于射频通信系统中。
In order to reduce the interference of wireless communication and to realize the multi-system sharing and transmitting receiving sharing for multi-wireless communication systems, the antenna must work under broadband and different frequency. In this paper, a novel dual-band microstrip antenna with good performance is analyzed and designed, and this antenna has been simulated by using the software HFSS 10.0. The simulation result shows that the frequency channels of the antenna are 1.67~1.84 GHz and 2.33~2.53 GHz, and the relative bandwidths of the antenna are 9.71% and 8.23%, respectively. This antenna can be used in RF communication as a multi frequency antenna.
