Abstract

The ever-increasing development of wireless and mobile communications, along with the rising volume of data and data traffic in wireless networks, requires these communications to be fast and uninterrupted. This can be achieved through the development of antennas with low return loss, high bandwidth, and compact size. In this study, an antenna design operating at a 2.4 GHz frequency was created using the CST Microwave Studio program to meet the need for broadband microstrip patch antenna designs. FR-4 material, which is 1.6 mm high, has a dielectric constant of 4.3 and a rectangular geometry with a loss tangent of 0.019, was used as the substrate material. At a resonance frequency of 2.4 GHz, the antenna was found to have a maximum gain of 2.27 dB and a maximum directivity of 7.28 dB in the same direction. Selection of new microstrip patch antenna configurations and development of accurate and versatile analytical models are of great importance in wireless communication technology.
