Proof of Concept of a Low-Cost Beam-Steering Hybrid Reflectarray that Mixes Microstrip and Lens Elements Using Passive Demonstrators
(2022-02-11)
In this article, a proof-of-concept study on the use of a hybrid design technique to reduce the number of phase shifters of a beam-scanning reflectarray (RA) is presented. An extended hemispherical lens antenna with feeds ...
Robust Multi-Beam Multiplexing Design Based on a Hybrid Beamforming Structure with Nearly Equal Magnitude Analogue Coefficients
(2022-02-10)
One novel design considering two practical application constraints based on the interleaved subarray architecture is proposed to achieve multi-beam multiplexing for arbitrary directions to serve corresponding users. One ...
