I. Introduction (Heading 1)
The IoT communication system relies heavily on the integration of 5G antennas, which are considered essential components due to their increased reliability compared to 4G antennas. To evaluate the performance of these antennas, simulations using CST studio software are conducted, measuring crucial parameters such as return loss, gain, direction, and radiation pattern. Among the various antenna types employed in 5G applications, the microstrip patch antenna stands out for its efficiency and ability to deliver optimal performance [1]–[5]. Notably, this antenna design exhibits impressive results in terms of radiation pattern, antenna gain, directivity, and return loss, further solidifying its suitability for 5G deployments within the IoT communication system.
