1×8 Slotted Array Antenna with Fan-Beam Characteristics for 28 GHz 5G Mobile Applications

A quasi-Yagi slotted array antenna with fan-beam characteristics for 28 GHz 5G mobile applications is proposed. The antenna is composed of a 1×8 slot antenna array with directors to enhance the half-power beamwidth (HPBW). The proposed antenna has a fan-beam radiation pattern with a simulated HPBW of 256.72° and a peak gain of 11.16 dBi. In addition, the proposed antenna covers ±48° using a beam steering mechanism. Mutual coupling reduction is achieved by inserting slits between the adjacent slot radiators on the ground plane.
