摘　　要：提出了1种采用集成基片间隙波导(ISGW)过孔探针馈电的圆极化贴片天线。该天线是通过在ISGW的上层介质板的上表面PEC层上蚀刻1个圆形缝隙,然后在中间放置矩形切角贴片,通过金属过孔与ISGW内部的微带线相连形成过孔探针馈电。仿真结果可以看出该天线的阻抗带宽为20%,轴比带宽为7%,在工作频段内增益比较稳定,最高增益可达到8.4 dBi。A circularly polarized patch antenna is proposed which is fed by an integrated substrate gap waveguide(ISGW)via probe.The antenna is formed by etching a circular slit on the upper surface PEC layer of the upper dielectric plate of the ISGW,and then placing a rectangular chamfer patch in the middle,and connecting the microstrip line inside the ISGW through the metal via to form a via probe feed.The simulation results show that the impedance bandwidth of the antenna is 20%,the axial ratio bandwidth is 7%,the gain is stable in the working frequency band,and the peak gain can reach 8.4 dBi.
