Broadband CP crossed‐stepped‐dipole antenna incorporating a cross slotted square patch
IET Microwaves, Antennas & Propagation, 2019 A simple broadband circularly polarised (CP) crossed‐dipole antenna is proposed. The antenna is composed of two crossed‐strip dipoles with two stepped sections, which are connected by vacant‐quarter rings to realise CP radiation, and a parasitic cross ...
