Abstract

This article presents a new wide E-plane beamwidth rectangular microstrip patch antenna adopting H-shaped gap-coupling with three parasitic patches for the K-band vehicle parking monitoring system, while keeping single substrate. Both side and upper parasitic elements serve as λ and λ/2 resonators and are excited primarily by magnetic and electric couplings, respectively. The synthesis of radiation patterns from main and auxiliary elements results in the E-plane wide-beamwidth property. The proposed gap-coupling antenna provided the peak gain of 4.82 dBi, E-plane half-power beamwidth (HPBW) of 143.4°, and co-to-cross-pol ratios of 22.7 and 20.2 dB within the HPBW for the E- and H-planes, respectively. The presented geometry showed excellent figure of merits compared with others for the K-band.

基于h型间隙耦合的k波段宽e平面波束宽度微带贴片天线

本文提出了一种新的宽e平面波束宽度矩形微带贴片天线，采用3个寄生贴片的h形间隙耦合，用于k波段车辆停车监控系统，同时保持衬底单一。两侧和上部寄生元件分别作为λ和λ/2谐振器，主要由磁耦合和电耦合激发。主元件和辅助元件的辐射方向图的合成导致了e平面的宽波束宽度特性。所提出的间隙耦合天线的峰值增益为4.82 dBi, E面半功率波束宽度(HPBW)为143.4°，E面和h面半功率波束宽度内的共交比分别为22.7和20.2 dB。所提出的几何图形在k波段上与其他几何图形相比具有优异的性能。
