摘要

提出了一种十字形缝隙加载的小型宽带及圆极化微带贴片天线的设计方法。该天线通过在方形贴片上加载一个大尺寸的十字形缝隙实现天线的尺寸缩减，介质基片采用由FR4和空气层组成的层叠结构，在缝隙中嵌入L型枝节，只需通过调整枝节上同轴线馈电点的位置来获得圆极化或宽带阻抗匹配。ANSYS HFSS仿真分析表明，天线的圆极化带宽（AR≤3 dB）为1.7%，阻抗带宽（VSWR≤2）为5.8%，天线在宽带范围内具有稳定的增益，峰值增益为7.8 dB，同时贴片面积缩减了52.3%。改变馈电点的位置可调节两个谐振频率使天线阻抗带宽达到9.4%，比传统的微带贴片天线阻抗带宽提高了114%。

Abstract

The design method of a compact cross slot broadband or and circularly polarized microstrip patch antenna was presented.A wide cross-shaped slot was embedded on the square patch for size reduction.The substrate was a stacked structure of an FR4 and an air layer.An L-shaped strip was added in the slot and only by changing the feeding point on the strip

circular polarization or broad impedance bandwidth can be obtained.ANSYS HFSS simulation results show that the circular polarization bandwidth（AR≤3 dB）and impedance bandwidth（VSWR≤2） were 1.7% and 5.8%

respectively.The antenna had stable power gain within a broad bandwidth and its peak power gain was 7.8 dB.Meanwhile

52.3% patch area reduction can be achieved.The impedance bandwidth can be improved to 9.4 % by varying the feeding location and adjusting the two resonance frequencies of the antenna.Compared with traditional microstrip patch antennas

the impedance bandwidth was improved 114%.
