MTM-Inspired Beam-Steerable SWB Smartphone Antenna Array for 5G/6G Cellular Communications

Phased arrays with broadband and super-wideband (SWB) capabilities, featuring extensive scanning and end-fire radiations, are imperative to meet the evolving demands of future cellular systems. This paper explores the properties of a new design, incorporating low-profile and SWB resonators tailored for advanced 5G communications. Its methodology is uncomplicated and executed seamlessly on the mainboard of prospective mobile handsets. The design comprises eight MTM-inspired dipole resonators arranged in a
$\mathbf{1}\times \mathbf{8}$
linear configuration. Covering a broad frequency band from 23 to 45 GHz with a -10 dB threshold, this design spans multiple bands within the 5G and 6G spectra. Beyond the straightforward design process, the phased array's intrinsic features aim to address the multifaceted requirements of future wireless systems.
