Novel 11 GHz 2-port antenna array integrated at a corner of mobile phone casing by LIM technologies of ITRI with diverse end-fire radiation patterns

摘要: This article presents a novel 11 GHz 2-port antenna array design for mobile phone applications with diverse end-fire radiation patterns. The constructed prototype uses LIM (Laser Induced Metallization) technologies of ITRI to implement two symmetrical patch antennas closely integrated at both side areas corner casing successfully. grounds and radiating patches are respectively formed on inside outside surfaces the without occupying limited available space circuit board. Good isolation can also be achieved between ports. proposed solution used MIMO, beamforming or beam-switching in future.
