Dual-Band Dual-Sense Polarization Reconfigurable Circularly Polarized Antenna

IEEE Antennas and Wireless Propagation Letters, 2019
This letter presents a novel dual-band circularly polarized slot antenna. The far-field polarization of the antenna can be switched electronically between left-hand circular polarization and right-hand circular polarization. A 50 Ω microstrip feed line is divided into four arms those excite a ground plane slot.

Dual-Band Dual-Mode Antenna with Polarization Diversity

Radioelectronics and Communications Systems, 2021
A compact dual-band dual-mode and dual-polarized (DBDMDP) antenna based on an asymmetrical Y-shaped microstrip line feeding along with a square ring radiator is proposed. The structure is loaded with two pairs of L-strips to extend the lower mode bandwidth (center frequency fc = 9.36 GHz).

Analytic Design Of Dual-Band, Dual-Polarized Lp-to-Cp Polarization Converters

2020 14th European Conference on Antennas and Propagation (EuCAP), 2020
A systematic procedure for the design of dual-band, dual-polarized linear-to-circular polarization converters is presented. This class of polarizers can convert linear polarization to orthogonal circular polarizations in two separate frequency bands. The polarization converter is composed of three electric admittance sheets.

Dual Band Dual Circularly Polarized Antenna with a Meanderline Polarizer

2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018
In this work a dual band circular polarized array antenna is presented. The proposed terminal consist of an array antenna in which the radiating elements operating around 20GHz and 30GHz are nested one into the other in order to form a dual band antenna. A meander-line polarizer is used to realize circular polarization.
