摘要 研究了一种新型共面波导馈电的宽带圆极化毫米波平面缝隙天线。通过新型的短路微扰法实现了平面圆环形缝隙天线的单馈宽带圆极化,回波损耗(RL)≤-10dB时的实测阻抗带宽达到约20%,AR≤3时的实测轴比带宽约为21.2%,实测最大增益约为5.2dB。实测结果与ANSOFTHFSS软件仿真结果基本吻合,表明了设计的合理性。 A novel CPW-fed millimeter wave slot antenna for broadband and circularly polarized radiation is discussed. Through a special short-circuiting stub perturbation method, the circular ring slot antenna achieves a broad impedance bandwidth of 20% with RL≤ -10dB and CP bandwidth of 21.2% with AR≤3dB, the measured peak gain of the antenna is about 5.2dB.
