Abstract

The aim of this project is to design compact UMTS antenna for cellular application. The feeding method used for this project is coaxial probe feed. The antenna consists of four layers which are the ground, substrate, copper and folded dipole. The ground and dipole fully employ copper with 0.32 mm thickness while the FR4 substrate has 1.6 mm thickness. The antenna provides a 15% bandwidth at S11 < -10 dB from 1885 MHz to 2250 MHz, which completely encompasses the desired UMTS frequency band (1920-2170 MHz). The basic configuration of this antenna is four folded edge and slotted rectangular antenna. The VSWR, input impedance, radiation patterns and S11 performance are used for the analysis of different configuration. Feed point on the dipole gives a good match of 50 Ω impedance. In the future, this project will bring advantage in telecommunication technology as it comes with a small size and good overall performance.
