Abstract


In this paper, a MIMO broadband array antenna has been studied, manufactured, and analyzed. The implementation of MIMO broadband array antenna has been applied for a four-port feed line in order to reduce interference between the bandwidth signals. In order to improve it, the chosen bandwidths have been (2.4 - 3.9) GHz, (7 - 11) GHz, and (20.7 - 30.61) GHz and the slots have been cut from the ground in order to gain 8dBi. The proposed antenna is made of an FR-4 material with the dimension of 40×40×1.6mm3, (r=4.3, tan (δ)=0.002 and the characteristic impedance of 50Ω for each port. The proposed MIMO broadband antenna array has been designed in order to be used for wireless communication applications. The obtained results are analyzed using CST software.
