Quad port meander line MIMO antenna with stepped ground structure for 5G wireless application

Every wireless communication system needs an antenna as a crucial component. High-performing antennas are needed for 5G to be used effectively, which is the newest technology trend. This study introduces a unique modified meander line planer patch antenna for 5G wireless applications operating at 3.0 GHz with return loss -39.5dB. The -10dB frequency spectrum of proposed antenna from 2.53GHz(f

substrate with thickness 1.524 is used to design proposed MIMO antenna. The requirements for the 5th generations wireless communication antennas are the lowest implementation costs, compact size, high gain and efficiency, broad bandwidth, low Envelope Correlation Coefficient (ECC), high isolation between ports. An improved results show the reliability of the proposed antenna for 5G applications
