Design of A 2.4 Ghz Microstrip Patch Antenna for Wifi Communication Using Cst Studio Suite 2019

Abstract

In this era of modern communication, there is a need for antennas that are lightweight, affordable, and easy to install. Many transmission devices require antennas with these specifications, and those specifications can be found in microstrip antennas. This antenna is commonly used in satellite communication, radar communication, military applications, and smartphones. However, the weakness of the microstrip antenna is its low gain, which is only about 5 dB. The design of the microstrip antenna is carried out using three methods: simulation, measurement, and fabrication. In this research, a microstrip patch antenna is designed to operate at a frequency of 2.4 GHz. The desired specifications are as follows: VSWR ≤ 2, return loss ≤ -10 dB. In the realization process, FR-4 substrate material with a thickness of 1.6 mm was used. At the end of the research process, a comparison was made between the simulation results and the measurement results. The simulation results from the antenna show that the VSWR is 1.545 with a return loss of -13.380 dB.
