K.Anil kumar,  N.Pavan kumar
In this paper, a compact circular ring monopole antenna for C band applications has been presented. The proposed antenna composed of two circular ring radiating patches separated by a radius of 0.5mm on FR 4 substrate with a dielectric constant of 4.4. The dimensions of the substrate are 20×20×0.8 mm3. It resonates at two frequencies of 4.4GHz and 7.3GHz in C band with the fractional bandwidths of 14.15% and 5.4% respectively. Return loss of the proposed antenna is -19db at 4.4GHz and -21.5db at 7.3GHz. Gain of the antenna is about 2.5db. ANSOFT HFSS13.0 software is used for the simulation of antenna.
