A Low-Profile Wideband Phased Array Antenna Using EBG Structures in P-band
In this paper, a wideband low-profile phased array antenna based on EBG Structures is presented in P-band. The antenna consists of three monopole antennas standing above a wideband mushroom-type electromagnetic band-gap (EBG) reflector. Compared with the perfect electric conductor reflector, the profile thickness of the presented antenna is greatly reduced by 78% from 0.23λ0 to 0.055λ0, where λ0 refers to the wavelength at center operating frequency. A phase-shift power divider is employed to feed the proposed antenna array, giving rise to the tilted radiation beam at around 30° in H-planes. This antenna is designed to operate with bandwidth from 0.53 GHz to 0.9 GHz (51.7%), with the gain over 5dB over a majority of bandwidth.
