Design of a Quadrilateral Patch Microstrip Antenna at a Frequency of 2.4 GHz for Wifi Signal Amplifier

Abstract

In the current information age, humans need communication to exchange information anywhere, anytime and with anyone. One of the communication systems that is a mainstay for the implementation of a global telecommunications system integration is the wireless communication system. Where in communication, a device that can capture wireless waves is needed, an antenna is used as a connecting medium. One of the wireless that is widely used today is wireless LAN or usually abbreviated as WLAN, where the antenna used in the WLAN application is pretty much designed like a microstrip. In this research, a rectangular patch microstrip antenna will be designed using the microstrip line feed technique, which is expected to work at a frequency of 2.4 GHz using the FR-4 Epoxy substrate type where h = 1.6 mm and ε_r = 4.6. From the research results, it is found that by doing optimization on the patch is able to provide better results when compared to the conditions before optimization. So that the return loss value is -34.23 dB, VSWR 1.04, impedance 50.552 Ω and gain -0.8073 dB. Keywords: Wireless, Microstrip, rectangular, Return Loss, Gain.
