摘　　要：文章设计一种宽带双圆极化印刷单极子天线,并进行加工制造和测试.天线整体尺寸为35.0mm×35.2mm×0.5mm,主体结构由倾斜开槽的半圆单极子贴片和开槽的金属地组成,可以实现天线优异的圆极化特性,仿真和实测结果表明,该天线S_(11)<-10dB的阻抗带宽高达65.8%(3.00~5.94GHz),3dB轴比带宽为61.3%(2.92~5.50GHz);将上述天线单元顺序旋转和平移,制作四端口宽带双圆极化天线阵列,仿真和测量结果表明,天线阵列在S_(11)<-10dB时阻抗带宽达到74.2%(2.80~6.10GHz),3dB轴比带宽为52.6%(3.50~6.00GHz).2种天线的仿真和测试结果高度一致,验证了文章设计理念的正确性.In this paper,a wideband dual circularly polarized printed monopole antenna is designed,manufactured,and tested.The overall size of the antenna is 35.0 mm×35.2 mm×0.5 mm.The main structure of the antenna is composed of an inclined slotted semicircular monopole patch and slotted ground layer,which is very helpful for the antenna to achieve excellent circular polarization characteristics.The simulated and measured results show that the S_(11)<-10 dB impedance bandwidth is as large as 65.8%(3.00-5.94 GHz),and the 3 dB AR bandwidth is 61.3%(2.92-5.50 GHz).On the basis of the above antenna unit,after sequential rotation and translation,a four-port wideband dual circularly polarized antenna array is also fabricated and measured.The antenna array exhibits a S_(11)<-10 dB impedance bandwidth of 74.2%(2.80-6.10 GHz)and a 3 dB AR bandwidth of 52.6%(3.50-6.00 GHz).The simulated and measured results of the two antennas are highly consistent,which validates the correctness of the design concept.
