Abstract
WLAN communication evolution can be analyzed from a variety of perspectives, but MIMO is crucial to that analysis because of its performance and assets. In multi-input, multi-output technology, higher data rates may be achieved depending on how transmitters and receivers interact, and precise results may be achieved. Using antenna arrays, we describe a firm 2×2 MIMO antenna structure where the S parameter is increased while the inter-element separation is 0.5 $\lambda$ mm. The design of the antenna is done in such a way that it serves IEEE 801.11ax applications and that compromises of standards, which are Wi-Fi6 or Wi-Fi6e, whereas Wi-Fi6 operates at two different frequencies, i.e., 2.4 GHz and 5 GHz, and now if we look into the modified standard version, which is Wi-Fi6e, it provides a third extended frequency band of 6 GHz, so it operates at the above frequencies. The proposed structure has a circular-shaped patch that utilizes a substrate of material called FR4, which has a permittivity of 4.4, and the substrate is placed at a height of 1.6 mm from the ground. The analysis and design of the proposed antenna are done using ANYSIS HFSS software.
