Quarter cylindrical dielectric resonator antenna with circular polarisation for wideband MIMO systems

, 2020
In this Letter, a quarter cylindrical dielectric resonator antenna (Q-CDRA) with a low profile and circular polarisation (CP) is presented for wideband and multiple-input-multiple-output (MIMO) systems.

Polarisation-independent liquid crystal lens array with additional dielectric films over self-aligned dual hole-patterned electrodes

, 2020
This study demonstrates a type of polarisation-independent liquid crystal (LC) lens arrays that are composed of two orthogonally homogeneous LC layers and self-aligned dual hole-patterned array electrodes.

Dual‐band circular polarisation generation technique with the miniaturisation of a rectangular dielectric resonator antenna

IET Microwaves, Antennas & Propagation, 2019
A technique is proposed to obtain the dual-band circularly polarised (CP) response along with the miniaturisation of a singly fed rectangular dielectric resonator (DR) antenna.

Substrate size selection of microstrip‐fed cylindrical dielectric resonator antennas for lowering the cross‐polarisation

IET Microwaves, Antennas & Propagation, 2019
A cylindrical dielectric resonator antenna (DRA) has been excited with a microstrip line in the HEM 11δ mode. It is demonstrated that at the operating frequency, minimum cross-polarisation occurs when the lateral dimension of the substrate is slightly ...
