Novel Design of High Performance of MIMO antenna for 5G Bio-Telemetry applications

Abstract

A MIMO antenna with 4 L-shaped elements and 2 E-shaped elements for the ISM band and also for wireless communication is proposed in the paper. This antenna contains 4 L slots in an H manner and 2 E slots are cut in the H slot. The dimensions of this proposed antenna are 40*30*1.6mm^3. The substrate used in this antenna is an FR4 substrate with a permittivity of 4.4. The operating frequency of this antenna is 2.4GHz and 5.1GHz.  All four L-shaped elements are placed in an orthogonal manner. The maximum gain is -4.4dB and the minimum gain is -16.2. The efficiency of this proposed antenna is 2.45. The radiation efficiency is 2.45dB and 75%. Fed can be provided using CPW. There is no need to concentrate on the isolation issue as we do not have several notches. This antenna is probably the most efficient antenna for the ISM band and also for wireless communication as a single-notch antenna is able to resonate at both frequencies.
