Transmitarray based Metasurface Lens Antenna
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019A transmitarray metasurface design is proposed to function as an integrated lens antenna within the frequency range of 11.6 GHz to 13.25 GHz. A finite periodic array of three-layer metallo-dielectric discrete unit cells is used to form the transmitarray lens.

Design of a Low-profile Transmitarray Antenna
2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall), 2019A low-profile transmitarray antenna consisting of single-layer substrate is proposed at 20 GHz. The element is formed by dual layers of cross rings and dipoles etched on the substrate and connected through metallic vias. The location and amount of vias as well as the dipole lengths are varied to realize a reasonable transmission phase swing and ...

Transmitarray Antenna with Rectangular Ring Patch at 28 GHz
2020 27th International Conference on Telecommunications (ICT), 2020In order to support the potential use of millimeter waves in future wireless communication systems, some explorations in antennas with enhanced gain are performed. In the last decade, the transmitarray antenna has been considered as a low cost and simple antenna that can support high gain by making an approach based on combination of two main concepts,
