Abstract

The aim of the project is to design a 2x2 array microstrip patch antenna operating at International Mobile Telecommunication (IMT 2000) Band whereby the frequency spectra is 1.885GHz to 2.172GHz. Since the microstrip patch antenna has various shapes, this project will focus for rectangular shape antenna and the feed network that connect through out the array is branching network power divider. The antenna is designed to become a base station for 3Gs system to replace the conventional antenna that mount on the building and communication tower. The 2x2 array antenna was designed using Microwave Office 2004 and achieved the bandwidth 4.65 % (VSWR 1.2:1 ). The antenna cover the frequency spectra of IMT 2000 from 1.885 GHz to 2.172 GHz The antenna was designed using FR4 board with dielectric substrate, Er = 4.7, loss tangent 0.019 and thickness 1.6 mm.
