A Broadband Low Profile Transmitarray Based on SIW Structures
2022 Photonics & Electromagnetics Research Symposium (PIERS)（2022）
Abstract
A low profile transmitarray antenna (TA) with high polarization purity and wide operational band is designed. It is available to obtain adjustable beam scanning and polarization selectivity, which are of vital importance for radar detection and environmental adaption. The TA is designed with partially reflective surface (PRS) element based on substrate integrated waveguide (SIW), the electromagnetic wave is fed and transmitted through aperture coupling. A compact low profile TA with reduced element coupling is thus obtained. The SIW based phase delay is also utilized here to cover a continuous 360 degree phase range.
