Abstract

Ultra-Wide Band (UWB) technology is rapidly developing area in the field of Wireless Communication. There are many challenges in this field, one of the challenges is to design an antenna which covers the entire UWB frequency range. The objective of this thesis is to design UWB antennas that operates in the frequency range from 4.0 GHz to 12.0 GHz. The proposed antenna is simulated using CST Microwave Studio Software. The antenna has been fabricated by using etching process and FR-4 as substrate. For measurement results, the Vector Network Analyzer (Agilent) is used to determine the S-Parameter, meanwhile for radiation pattern was measured in anechoic chamber. This thesis covers study of basics and fundamentals of microstrip patch antenna, in this paper rectangular microstrip patch antenna with defected ground structure (DGS) which is Y-shaped for ultra-wide band (UWB) application is presented. A comparative parametric analysis has been made based on return loss, gain, radiation pattern characteristics and impedance bandwidth. Simulation results and measurement results are analyzed and confirm the validity of the proposed antenna.
