Abstract

A novel compact planar printed gap coupled rectangular monopole microstrip antenna (CPGCRMSA) for ultra wideband (UWB) broadband operation is presented in the paper. The antenna is designed using FR4 substrate with dielectric constant 4.2, loss tangent 0.05 and a height of 1.6 mm. The designed antenna is simple in its geometry and can be constructed by splitting the rectangular monopole MSA vertically and horizontally along the width and length of the radiating patch. By proper gap coupling these splitted parasitic patch elements the UWB operation can be achieved. The antenna operates in the frequency band of 1.82GHz to11.83GHz and gives maximum impedance bandwidth of 146.6%and peak gain of 8.50 dB in its operating band. This antenna exhibits nearly omnidirectional radiation characteristics over the entire frequency band. The simulated and measured results are presented. The measured results are in well agreement with the simulated results. The proposed antenna may find application in Bluetooth, WiMax, WLAN, X-band Satellite Communication.
