摘要
针对UHF频段双频双圆极化微带天线的设计目标 ,本文利用增大基片厚度、降低基片相对介电常数来实现双频覆盖 ,采用口径耦合馈电形式来实现双圆极化。文中给出了AnsoftHFSS 8.0的仿真结果以及实际的测试数据。天线已在”创新一号”小卫星地面终端中得到了应用。
The paper aims at the design of dual frequency and dual circular polarization antenna. Dual frequency covering can be achieved with a single patch using a relatively thick low dielectric constant substrate. Coupling apertures are used to realize dual circular polarization. The results simulated by Ansoft HFSS 8.0 and the measured data are presented. The antenna has been used in the terminal of ChuangXin No.1 microsatellite.
