Design and Implementation of T-Shaped Planar Antenna for MIMO Applications

This paper proposes, demonstrates, and describes a basic T-shaped Multi-Input and Multi-Output (MIMO) antenna with a resonant frequency of 3.1 to 10.6 GHz. Compared with the U-shaped antenna, the mutual coupling is minimized by using a T-shaped patch antenna. The T-shaped patch antenna shapes filter properties are tested to achieve separation over the 3.1 to 10.6 GHz frequency range. The parametric analysis, including width, duration, and spacing, is designed in the MIMO applications for good isolation. On the FR4 substratum, the configuration of MIMO is simulated. The appropriate dielectric material ɛr = 4.4 is introduced using this contribution and application array feature of the MIMO systems. In this paper, FR4 is used due to its high dielectric strength and low cost. For 3.1 to 10.6 GHz and 3SRR, T-shaped patch antennas are used in the field to increase bandwidth. The suggested T-shaped MIMO antenna is calculated according to the HFSS 13.0 program simulation performances. The antenna suggested is, therefore, a successful WLAN candidate.
