A millimeter-wave transmitarray antenna

2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2016
A 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, 2018
A 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.

Molding the optical transmission with a meta-transmitarray

2013 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2013
Summary form only given. Here, we propose a new route to locally manipulate the optical transmission amplitude and phase with unprecedented flexibility and efficiency. To achieve this aim, we extend the idea of radio-frequency transmitarrays (D. M.

Triple-layer transmitarray antenna designs

2014 United States National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM), 2014
The 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 ...
