A Design Framework for Beamforming Integrated Circuits Operating at Mm-Wave Frequencies
IEEE Access, 2021 In order to cope with the needs of fifth-generation (5G) cellular networks and beyond, phased-array antenna systems operating at millimeter-wave (mm-wave) frequencies will be required. This makes the system design very complex. In order to create insight

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 ...
