摘　　要：提出了一种具有新型多功能空间馈电平面的阵列天线,可以同时实现透/反射两个波束。该阵列通过快速响应编码对圆环反射单元和透射单元进行合理分布,以实现不同极化方向的透/反射波束。基于所提出的透射和反射单元,设计并制造了具有25×25个单元的透射-反射阵列天线,分别产生θ=0°向后的x极化方向的反射波束和θ=180°向前的y极化方向的透射波束。该天线的中心频率为22 GHz,测试结果表明,反射波束最大增益为22 dB,3 dB增益带宽达到28%;透射波束的最大增益为19.2 dB,3 dB增益带宽达到27%。A new multi-functional space-fed planar array antenna with the ability to transmit/re-flect two beams simultaneously was presented in this paper.The double-ring reflection units and trans-mission units were reasonably distributed by fast response coding to realize the transmitted/reflected beams in different polarization directions.Based on the proposed transmission and reflection units,a transmission-reflection array antenna with 25×25 units has been designed and fabricated to produce a reflected beam in the x-polarization direction withθ=0°backwards and a transmitted beam in the y-polarization direction withθ=180°forwards,respectively.The center frequency of the antenna is 22 GHz and the test results show that the maximum gain of the reflected beam is 22 dB and the 3 dB gain bandwidth reaches 28%;the maximum gain of the transmitted beam is 19.2 dB and the 3 dB gain bandwidth reaches 27%.
