DUAL BAND ANTENNA FOR 4G/5G WIRELESS COMMUNICATIONS AND DEFECTED CENTER COAXIAL FILTER

摘要

A dual band microwave/millimeter wave antenna for next generation wireless systems. The antenna assembly has a low frequency monopole antenna and a sleeve with high frequency antenna arrays. A three-sided sleeve monopole antenna provides omnidirectional radiation patterns from ˜1.7-2.7 GHz, and each side of the sleeve monopole incorporates two series-fed linear patch arrays operating at ˜27.5-28.35 GHz. The sleeve monopole provides 3G/4G/LTE coverage while the patch arrays provide sectored MIMO 5G coverage.
