Design and Build of 2400 MHz Yagi Antenna for WiFi Communications Receiver

Rancang Bangun Antena Yagi 2400 MHz Untuk Receiver Komunikasi WiFi

Abstract

Wireless Local Area Network (WLAN) is a wireless local area network that uses radio frequencies as its transmission medium. In this study, we design a wifi network in the Sriwijaya State Polytechnic Lecturers Housing, whose wifi beam is from the Sriwijaya State Polytechnic campus, so that the lecturer housing can access wifi without the need to come to campus. As wifi communication receiver, the role of the antenna is needed in a long-distance wireless communication system, the antenna used is a yagi antenna that works at a frequency of 2400 MHz. Yagi antennas were chosen because of their directional nature or their directional beam pattern. In designing yagi antennas for the reflector, driven, director, and balun sizes, the yagi calculator software is assisted and simulated, and tested using MMANA-GAL to produce more accurate antenna parameters. This yagi antenna will then be connected to an access point that is set up as a client to receive signals from the transmitter and router as a routing process so that users in lecturer Housing can access the wifi. Based on the results of the MMANA-GAL yagi antenna with a frequency of 2400 MHz, the Standing Wave Ratio (SWR) is 1.16 and the Gain is 14.59 dB.
