Dual-Band Phased Array 5G Mobile-Phone Antenna with Switchable and Hemispherical Beam Pattern Coverage for MIMO-Diversity Communications

A new design of dual-band antenna array with 3D-coverage beam steering characteristic for millimeter-wave (MM-Wave) communications is proposed in this manuscript. The covers frequency bands 18 GHz and 28 GHz. Its configuration contains three subarrays patch radiators along the edge area smart phone printed circuit board (PCB). Each sub-array eight elements antennas C-shaped slots. resonant frequencies single element radiator can be adjusted by tuning sizes embedded slot main radiator. beam-steerable designed on an N9000 PTFE dielectric. In order to achieve high gain beams also covering wider beam-steering area, each deployed different top-sides PCB a dimension 55××110 mm22. Using uniform linear sub-arrays, hemispherical pattern coverages achieved. provides good performances terms gain, radiation total efficiencies, properties which make it suitable use fifthgeneration (5G) mobile-phone platforms.
