A Novel Folded Transmitarray Antenna
2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019In this paper, a novel folded transmitarray antenna is presented. The proposed transmitarray antenna consists of a transmition array with carrying polarized grid, a feed antenna and a polarization rotation reflection surface (PRRS). First, a unit cell consisting of three traditional double-ring phase shift structures and one polarizer grid etched on ...

A millimeter-wave transmitarray antenna
2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2016A broadband and high gain transmitarray (TA) antenna, operating at 60 GHz, is presented. As a constituent part of the TA, a multi-layer unit cell (UC) is optimally designed to realize a linear transmission phase response with a continuous variation range of at least 270 ° and a transmission loss less than −3 dB across the desired frequency range from ...

High-Efficient Wideband Transmitarray Antenna
IEEE Antennas and Wireless Propagation Letters, 2018A new structure for transmitarray antennas is presented. The proposed semiplanar transmitarray keeps certain geometrical curvature, that the required transmission phase range is reduced significantly from 360°, causing an increase in bandwidth and efficiency.

Triple-layer transmitarray antenna designs
2014 United States National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM), 2014The goal of this work is to reduce the complexity and cost of transmitarray antennas by decreasing the number of layers. Three different methods are used to design triple-layer transmitarray antennas, while maintaining the overall performance with full transmission coefficient phase range of 360° and avoiding the reduction of the element transmission ...
