Rancang Bangun Antena Stacked Turnstile Pada Frekuensi 2,4 GHz Untuk Aplikasi WIreless Local Area Network (WLAN)

Abstract

The purpose of this research is to design an antenna that will be used as a transmitting antenna that can level up the receiver. The designed antenna is a stacked turnstile antenna that has again of 3dB from previous studies. At the turnstile antenna using a power divider to raise the antenna gain of 1.5dB. Power divider is used Wilkins on power divider with a vertical stack. The stack distance used is0.6?. From the results of the implementation of the AntennaLaboratory of the Polytechnic of Malang, a stacked turnstile antenna produces vertical polarization and omnidirectional radiation patterns. Value of the measured return loss is-13.8dBat a frequency of 2,384MHz. Additionally stacked turnstile antenna has a value of 4.83dBi gain. VSWR values were measured at a frequency of 2,384GHz is 1,091 and has 425MHz bandwidths frequencies ranging from 2275 to 2700MHz. Level of signal reception at the access point-Link TL Type WA 5110G higher than 4dbm antenna access point, while stacked turnstile antennas transmitting antenna at a maximum distance of 100m to get the signal reception is better than 84dB antenna access point signal reception-89dB.
