摘要

针对矩形微带天线的变化,提出了近馈等边三角形微带天线的间隙耦合设计。等边三角形微带天线的设计提供了302 MHz(25%)的带宽和7.6 dBi的宽侧增益。通过缝隙耦合矩形贴片实现带宽和增益的增强。在相邻两层矩形贴片和四层矩形贴片的间隙耦合配置下,VSWR带宽大于670 MHz(57%),峰值增益为9.7 dBi。所提出的设计在实现上更简单,测量结果显示出非常接近的一致性。

Proximity Fed Broadband Equilateral Triangular Microstrip Antenna Using Parasitic Rectangular Patches
Gap coupled design of proximity fed equilateral triangular microstrip antenna along with variations of rectangular microstrip antennas are proposed. Design of equilateral triangular microstrip antenna provides a bandwidth of 302 MHz (25%) with broadside gain of 7.6 dBi. Enhancement in bandwidth and gain is realized by gap coupling rectangular patches. Optimum result with VSWR bandwidth of more than 670 MHz (57%), showing peak gain of 9.7 dBi is obtained in gap coupled configuration with two adjacent layers of two and four rectangular patches. Proposed design is simpler in implementation and measured results show close agreement.
