Abstract
In this article, a 15 × 20 mm2 arbitrary-shaped antenna is built. The same is extended to a 2 × 2 MIMO antenna with size 32 × 20 mm2. It covers two bands. Band-1 covers 3-4.44 GHz, and band-2 covers 5.32-11.1 GHz. In this case, a circular neutralization structure is used to lessen the mutual coupling between the two ports. The ECC, DG, CCL, and radiation pattern are used to demonstrate how well the MIMO antenna performs. Also, it has been noted that there is good agreement between simulated and measured outcomes.
