Abstract

In this paper, a multi resonant MPA capable of operating in a frequency range of 3 GHz to 7 GHz have been proposed. The antenna has been designed using substrate of FR4 material having dielectric constant of 4.4 with radiating patch and a ground plane. The ground plane has been partially reduced to improve the antenna performance. The antenna has a feed line which is connected to patch. The feed line has to be of suitable width so as to match the antenna impedance with the port impedance (50 ohm).The feed line thickness is same as that of the patch thickness. The antenna performance has been analyzed in terms of various antenna parameters such as return loss (dB), impedance bandwidth (GHz), gain (dB), directivity (dBi) and VSWR. The antenna has been designed and simulated using CST Microwave Studio (2010).The designed MPA is suitable to be used for IMT, WLAN standard and WiMAX applications. The antenna has a bandwidth of 4.01GHz and VSWR is less than 2. Theantennahasbeenfabricatedandtested.Ithasbeenob servedthatthepracticalresultsobtainedbytesting the fabricated antenna using Network analyzerE5071C closely matches with the theoretical results obtained by simulating the antenna design in CST MWS 2010.
