Design of MIMO Antenna with Reflector-based Isolation Technique for mm-Wave Applications
Keywords:
Antenna, Isolation Technique, MIMO antenna, Reflector.Abstract
This work is focused on mutual coupling reduction among the antenna ports at mm-wave frequencies, which are frequencies of interest for 5G communication. Initially, the design and simulation of a single-port T-shaped wideband antenna resonating at 26 GHz with a frequency range of 24-28 GHz have been presented for possible Multiple Input and Multiple Output (MIMO) applications. The single-port wideband antenna has been extended to four-ports, and a reflector approach has been utilized to lessen mutual coupling. This isolation strategy reduces the mutual coupling by 5 dB, which is verified through software simulations. The isolation enhancement is also verified using surface current distributions.
