High‐Efficiency Magnetoelectric Dipole Antenna Array With Passive Beam‐Switching for 5G Applications
This paper presents a 2D scanning array of magneto‐electric (ME) dipole antennas designed for 5G millimeter‐wave applications. The design features a Butler matrix comprising four hybrid couplers, realized as a printed ridge gap waveguide (PRGW) matrix, thereby achieving a phase error within ±6° across the 27–33 GHz fre...
