设计了一种具有极化转换功能的圆极化透射阵天线单元。该单元具有3层结构,包括线极化接收贴片、地板和圆极化辐射贴片,通过旋转圆极化辐射贴片来实现相位补偿。采用该单元设计了一种具有极化转换功能的圆极化透射阵天线,并对其进行了仿真。仿真结果表明,在10 GHz处天线的增益和口径效率达到最高,分别为24 dBi和31%,天线的3 dB增益带宽为9%(9.6～10.5 GHz)。与一般的透射阵天线相比,该透射阵的焦径比仅为0.33,具有剖面低的优点。对该天线进行了加工和测试,测试结果与仿真结果基本吻合。
Abstract：A Circularly Polarized Transmitarray Antenna(CPTA) element with polarization conversion function is designed.The element has a three-layer structure, including a linearly polarized receiving patch, a ground plate and a circularly polarized radiation patch.The circularly polarized radiation patch is rotated to achieve phase compensation.A CPTA with polarization conversion function is designed by using this element and simulated.The simulation results show that the gain and aperture efficiency of the antenna reach the highest values at 10 GHz, which can reach 24 dBi and 31%,respectively.In addition, the 3 dB gain bandwidth of the antenna is 9%(9.6～10.5 GHz).Compared with the general transmitarray antenna, the focal diameter ratio of the transmitarray is only 0.33,which has the advantage of low profile.The antenna has been manufactured and tested, and the test results are basically consistent with the simulation results.
