PENGGABUNGAN ANTENA MIKROSTRIP PATCH RECTANGULAR DAN CIRCULAR UNTUK APLIKASI WLAN 2,4 GHz

Abstract

Antena is a device used in the process of sending and receiving in telecommunications. One type of antena that is developing at this time is a type of mikrostrip antena. Mikrostrip antena has the advantage of being able to work at high frequencies and has a very small size so that the placement is very efficient. The mikrostrip antena is a combination of rectangular shapes and triangle shapes Design of the antena in this paper is used for WLAN applications which work at frequency of 2,4 GHz. Design of the antena using FR4 as substrate with dielectric constant 4,4. Antena simulations using CST Studio Suite 2017 as  softwate. Antena simulations shows return loss is -14,35 dB, VSWR 1,02 on frequency 2,4 GHz. Gain antena has 1,8 dBi. Power antena 0,45 Watt and Bandwidth 48MHz has Omnidirectional pola radiation and Impedance 50 Ohm. This model can continue to antena fabrication
