Abstract

A wideband low-profile transmitarray antenna is proposed based on the I-shape resonator. The design is composed of a transmitarray and a reflective surface (RS). In the transmitarray element design, the I-shape resonator is sandwiched by two orthogonal polarization gratings to provide continuous phase compensation. While in the RS element design, the I-shape resonator is also used to convert the polarization and manipulate the reflecting phase. By properly designing the phase distributions on both apertures, the profile of the antenna is reduced to 1/5 of the focal length. The simulated results show that the proposed transmitarray antenna can achieve a peak gain of 24.8 dBi, a peak aperture efficiency of 46% and a 3-dB gain bandwidth of 37%. Moreover, the final profile of the transmitarray antenna is about 1.2λ at the center frequency.
