摘要

介绍了一种小贴片阵列馈电发射阵列天线的设计方法。研究分析了由两个啮合的三环组成的发射阵列元件，通过调整内环的半径就可以实现285°的大传输相位范围。为了验证设计方法，在38.5 GHz频段设计了尺寸小于5×5 λ02的TAA。仿真结果表明，该天线在38.5 GHz时具有20.85 dBi的高增益，在37 ~ 40 GHz范围内保持小于±0.5 dB的增益纹波，是毫米波应用的理想天线。

A mmWave Transmitarray with Patch Array Feed

This paper introduces a design method of transmitarray antennas (TAAs) with a small patch array feed. The transmitarray element consisting of two meshed triple-circle rings is studied and analyzed to realize a large transmission phase range of 285° by tuning only the radius of the inner ring. To validate the design method, a TAA of size less than 5×5 λ02 is designed at 38.5 GHz. Simulated results show that the proposed TAA exhibits a high gain of 20.85 dBi at 38.5 GHz while maintaining a gain ripple of less than ± 0.5 dB from 37 to 40 GHz, indicating it is a good antenna candidate for mm-wave applications.
