a basic MIMO antenna with two elements with a compact arrangement is designed to improve the isolation and impedance matching. These two identical elements of the antenna are fed by the microstrip line feeding given to the altered radiating elements which are rhombic in shape. Placed in the compact substrate area of 0.24λ0 × 0.42λ0 (where λ0 is the value of λ at 3.6 GHz) on an allocated rectangular ground plane. The pair of antennas which are being designed are sundered by a T-shaped ground stub to strengthen the isolation and impedance matching and the central axis of each radiating element is provided with the U-shaped stub for attaining the desired resonant frequency of 3.51GHz. The antenna system which is introduced, extends to a -10dB operating band of 3.22 to 3.75 GHz (530 MHz) with isolation of 19.8dB between the pair of antenna elements are analyzed and also the performance of this basic MIMO antenna are validated and analyzed. The measured performances and simulated performance of the desired antenna are symmetrical to each other. This proposed antenna can later be realized for a 4-element MIMO antenna. In various fields of 5G applications such as mobile communications, space, and satellite communications.
