P.Vetriselvi, Sathiyamoorthy Murugan., Dr.V.Rajamani

The objective of the work is to design a wideband Rectangular Micro strip Antenna for covering wireless Mobile Applications. The proposed antenna geometry describes a coaxial fed rectangular patch printed over a FR4 substrate of thickness 1.6mm and permittivity εr=4.4.The design parameters for the antenna are length and width of the patch and slot. Broadening the antenna bandwidth is achieved by U-slot technique. The antenna analysis is carried out with full wave simulation Ansoft HFSS by using the parameters Return loss (dB), Bandwidth, VSWR, Radiation Pattern and gain. The antenna operating frequency range is 1.85GHz - 2.49GHz with VSWR less than 2. It exhibits wideband which corresponds to the gain of 5.48dB. It has wireless applications which require more bandwidth such as for covering all wireless applications of WiMAX, WiFi, WCDMA 3G, and some 4G LTE etc. The simulation results are compared for the performance of antenna.
