Due to the requirement for small, high-speed, and wide-bandwidth systems, communication technologies have been
pushed towards the fifth generation (5G). These types of radio communication systems demand new antenna designs that are
more efficient. Because of this, the new system will be able to work with more devices and meet the higher quality standards that
modern applications require. In this paper, Microstrip patch antenna designed in CST software, which is the better for time
domain based simulation.
