N2 - 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.
