Very Low Profile, Wideband, Dual polarized Massive MIMO Antenna Element with High Isolation for 5G Base Station Applications

Very low profile, wideband printed bowtie dipole dual-polarized aerial is offered for wideband BTS. A flared bow tie dipole with shorting post with Teflon spacer is proposed to attract low-profile geometry. The design incorporates a Pair of orthogonal printed Flared Bow Tie Dipoles are arranged in a ±45°and fed with two coaxial cables. Shorting posts and Teflon spacers above the ground plane is used to obtain high gain and directional stable emission model is proposed to attract low-profile. The designed Massive MIMO (Multiple Input Multiple Output) aerial element and 2x2 MIMO is designed and optimized on RT Duroid 5880 substrate is working for less than 6GHz (3.0-5.0GHz) for 5G BTS applications. From the simulation results the single aerial element with flared section on the dipole arms yields an S
₁₁
less than -15dB impedance properties of 45.95% (3.12-5.32 GHz), HPBW of 71.5° and a gain of 9.2dBi, with Isolation (S
₁₂
) of -37dB, with symmetrical wave's pattern. The overall height of the aerial is 0.25λ
₀
and the design is simple and easy to fabricate. Thus, this new design is an ideal candidate for the new 5G BTS applications.
