Very Novel Design and Mutual Coupling Analysis of a Wideband, Tightly Arranged DP massive MIMO (32T and 32R) Antenna Array for 5G Base Station Application

A Wideband, Tightly Arranged DP Massive MIMO (32T and 32R) Aerial Array for 5 G Base Station Application is provided with Very Novel Architecture and Mutual Coupling Analysis. The dual polarization is achieved by placing two chamfered aerial bow-tie dipole elements in orthogonal orientation and being fed with two coaxial cables. The design consists of chamfering the two arms of bow-tie aerials that enhance port isolation to port. The pattern of unidirectional radiation is obtained by placing a metal ground plane at a distance of λ/4. The radiating components are designed for operation at 3.5 GHz. Simulated tests of the expected dual-polarized chamfered aerial bowtie show a sub-6GHz bandwidth (2.84.0 GHz) with VSWR <; 1.5. Isolation between the two ports is-27dB and reciprocal coupling is around-25 dB and for both the polarization a gain of 9.1dBi is observed. The aerial overall height is 0.25λ
₀
and the design is simple and easy to manufacture. This Aerial is thus the most suitable for future 5G BTS implementations.
