摘要：
A CPW-fed slot-coupled millimeter wave (Ka band) patch antenna is discussed. The coupling slot is on the ground plane, hence there is no need for a couple slot layer. The presence of the coupling slot changes the current distribution on the ground plane, and the current is guided by the slot, the coupling between the feed part and the radiation part is enhanced. Ansoft HFSS, a high frequency structure simulation software based on Finite Element Method (FEM), is used to analyze the antenna performances. Variations of parameters such as: substrate thickness, bow-tie patch angle, coupling slot size, etc. are discussed. A set of parameters is given after comparing and analyzing the simulation results, such as S11 and gain of the antenna. The antenna works at the center frequency of 35.5 GHz, the bandwidth is 1.22 GHz, and the gain is 6.38 dB.
