A New Design Of T-Shaped Patch Antennas For 5G MIMO Applications

The design and optimization of T-shaped patch antennas for MIMO applications of contemporary wireless communication schemes are presented in this paper. Electromagnetic modeling systems have become essential for developing and improving wireless networks due to the rapid rise of wireless communication technologies, including 5G and beyond. A test Poisson’s ratio of 0.33, a Young’s modulus of 120 KN/mm2, annealed copper as a lossy metal, the electrical conductivity 5.8e+7 s/m, and a specific heat value of 390 [1/K/kg] are used in the preparation of the model for the antenna structure. T-shaped patch antennas (MIMO) are the type of antenna utilized in modern wireless applications. Two T-shaped antennas are put on top of a 37 × 44 mm2 FR4 substrate, which has a thickness of 0.035 mm. The unit cell is constructed with a width of 5.00 mm. The external lengths are 4.20mm and 3.45mm. The present study aims to reduce mutual coupling between two patch antennas by enhancing their isolation through the use of five meta-material unit cells. The two antennas operate at a frequency of 5.8GHz. Computer Simulation Technology (CST) software is used to simulate their antenna efficiency, realized gain, diversity gain, and surface current distribution at 99%, 4 dB, 9.99 dB, and 375 A/m, respectively.
