As a result of developments in communication systems in recent decades, the need for smaller, more lightweight, and higher-performance antennas has increased. One of the leading antenna types that can meet these needs is microstrip antennas. They provide many advantages such as their small size, easy to manufacture, and low cost. In addition to these advantages, they also have weaknesses such as low bandwidth. In this study, a rectangular microstrip patch antenna operating at 2.4 GHz resonance frequency is constructed. The antenna is designed on FR-4 substrate with a thickness of 1.6 mm and dielectric constant εr=4.4. It has three slots. Two on the patch and one on the ground plane. Desired patch antenna design is simulated by CST. The return loss of the designed antenna is –43 dB, and its bandwidth is 70 MHz.
