【摘要】 本文设计了一种用于卫星通信的小型圆极化天线,天线采用印刷偶极子垂直交叉结构,能够在344MHz～396MHz的频段实现圆极化,电磁仿真软件的分析结果表明天线在工作频段内驻波比小于2.2,收发隔离度大于35dB,增益大于3dBic,3dB轴比波束宽度达到120°,说明该方案是正确可行的。更多还原

【Abstract】 In this paper, a small-size circular polarization antenna for satellite communication is presented.The dual-polarized printed dipole antenna is designed with vertical cross structure. The proposed antenna Can realize circularly polarized simultaneously at 344 MHz-396 MHz. In the operating frequency band,the simulated results show that the isolation is more than35 dB,VSWR is less than 2.2, the radiation gain of the proposed antenna is larger than 3 dBc and the 3 dBic axial ratio beamwidth reach to 120 degrees.更多还原
