DUAL-BAND AND DUAL-POLARIZED MM-WAVE ARRAY ANTENNAS WITH IMPROVED SIDE LOBE LEVEL (SLL) FOR 5G TERMINALS

摘要

An antenna array and a user equipment (UE) including the antenna array. The antenna array includes a plurality of unit cells. Each unit cells includes first and second patches, phase shift transmission lines, a third patch, and a transmission line. The first and second patches radiate at a first frequency band and positioned in a first plane of the antenna array. The phase shift transmission lines connect the first and second patches and shift a phase of a signal between the first and second patches. The third patch is positioned in a second plane of the antenna array and beneath the first patch and radiates at a second frequency band that is lower than the first frequency band. The transmission line excites at least the third patch.
