Dual Band and Polarised Cross STDA MIMO System for the Base Station Antenna for 5G Communications

Abstract

A novel dual polarized cross STDA for the base station 5G application is presented in this paper. The resonant frequency of the proposed antenna is 3.3 to 3.8 GHz and 4.8 to 5 GHz with average realized gain 24 dBi and 26.5 dBi in the upper band and lower band respectively with the stable radiation pattern. It consists of two circular tapered dipole antennas with parasites element feed with adjusted balun system. In this design feed point are shifted along with the balun feed by adjustment. The three-dimensional cross-sectional area is 68 × 68 × 94 mm.
