A Multifunctional Array System Based on Adjustable-Phase Antenna for Wireless Communications

In this work, an innovative method for controlling the current distribution of radiating patch by adjusting input phase is investigated to achieve both pattern and polarization reconfigurable characteristics multifunction. A compact low-profile antenna with four fed ports designed implement proposed method, which can operate linear, right-hand circular (RHCP) left-hand (LHCP) different beam directions in operating band from 4.0 5.0 GHz. Even more, a four-by-four passive planar array fabricated based on element, scan coverage 70{\deg} low gain fluctuation sidelobe dual-polarization. Meanwhile, it realize wide-angle scanning capability up 60{\deg} RHCP LHCP. More important, dual- triple-beam be obtained array. Good agreement has been shown between measured simulated results. Therefore, good solution wireless communication systems because its simple-configuration, multifunction, beamforming capability.
