摘要
提出了一种新型的适合ISM 2.45 GHz频段的无线通信和RFID等领域应用的h形微带天线,该天线具有小型化、双频工作等特点。该h形微带天线被看作由两个半波微带振子组成,分别对应于天线的两个工作频率。文中给出了天线反射损耗的实测结果及实测方向图,实测结果与软件仿真及理论预测结果基本吻合。
A novel compact h-shaped dual-frequency microstrip antenna, which is suitable for wireless communication and RFID applications at ISM 2.45 GHz band, is investigated. This novel microstrip antenna is considered to be composed of two microstrip dipoles, which resonate at the antenna's two operating frequencies respectively. The resonant frequencies are predicted. Simulated and measured return loss of the h-shaped microstrip antenna and measured radiation patterns are presented and discussed, and good agreement is achieved.
