摘要

本文设计了一种在Rogers 5880基板上采用电容耦合槽激励的24ghz微带网格阵列天线。天线尺寸为70mm×70mm×0.787mm。15mm×0.3mm的电容耦合槽位于接平面的中间。在Ansoft HFSS上的仿真结果表明，在22 ~ 24.95 GHz范围内，其10 dB阻抗带宽为2.95 GHz;在24.4 GHz范围内，其最大峰值实现增益为18 dBi;在23.03 ~ 25.18 GHz范围内，其3 dB增益带宽为2.15 GHz。研究表明，槽激励是一种有效的微带网格阵列天线激励方法。

24-GHz microstrip grid array antenna excited by capacitive slot

This paper presents the design of a 24 GHz microstrip grid array antenna excited by capacitive coupling slot on Rogers 5880 substrate. The dimension of the antenna is 70mm×70mm×0.787mm. The capacitive coupling slot of 15mm×0.3mm is located in the middle of the ground plane. Simulation results in Ansoft HFSS indicate that its 10 dB impedance bandwidth is 2.95 GHz from 22 GHz to 24.95 GHz, the maximal peak realized gain is 18 dBi at 24.4 GHz and 3 dB gain bandwidth is 2.15 GHz from 23.03 GHz to 25.18 GHz with broadside radiation patterns at 24 GHz. This work demonstrates that slot excitation is an effective excitation method for microstrip grid array antennas.
