Hybrid Parasitic Linear Array Antenna for Fine Beamsteering Applications
(Institute of Electrical and Electronics Engineers (IEEE), 2021-06)
This paper presents an antenna that utilizes two beam steering techniques in concert in order to improve the antenna gain and steering resolution. Phased array steering is employed to achieve coarse resolution beam steering ...
Reconfigurable Liquid Metal Based SIW Phase Shifter
(Institute of Electrical and Electronics Engineers, 2021)
Abstract—This paper presents the first substrate integrated waveguide (SIW) phase shifter that can be reconfigured using liquid metal. This digital phase shifter exhibits low insertion loss and is reciprocal and bidirectional. ...
Analysis of the Transmission Performance Limits for a Multi-layer Transmitarray Unit Cell
(IEEE, 2021-09-01)
This communication presents a theoretical study that establishes the performance limits for a multi-layer transmitarray unit cell. This is the first study to be applicable to unit cells in which the conducting resonators, ...
