摘要
A high-gain and broadband linear-polarized transmitarray antenna is proposed in this paper, and its element is composed of 4 identical layers of E-shaped patches separated by quarter-wavelength air gaps. To cover the required phase range, the dual-resonant E-shaped element is developed; realizing broadband transmission, low cross-polarization level, and stable oblique-incident response. A transmitarray prototype using the 4-layer E-shaped element is designed, fabricated, and tested. The proposed transmitarray has a broad 1-dB gain bandwidth of 15%, a high gain of 33.0 dBi, an aperture efficiency of 40%.
