The proposed antenna is designed by using computer simulation technology software and then the prototype is fabricated and tested. Further the proposed antenna shows maximum gain and radiation efficiency values of 6.1 dB and 94% with stable radiation pattern over the entire band of operation. Experimental results show that the designed antenna covers the entire unlicensed UWB range from 3.1 to 10.6 GHz with five resonating dips at 3.4 GHz, 5 GHz, 6.5 GHz, 7.7 GHz and 9.3 GHz along with low return loss values (below − 20 dB) and improved input impedance of approximately 50 Ω at all frequencies. The antenna is designed using FR4 substrate having relative permittivity of 4.4 and has a small size of 30 mm × 30 mm × 1.6 mm. The initial structure of the antenna consists of a circular patch with radius 8.1 mm fed by 50 Ω strip line feed, which is modified further with multiple resonating structures to improve overall bandwidth, impedance matching, return loss, gain and radiation efficiency. This paper mainly focuses on the broad band impedance matching of an ultrawideband (UWB) antenna using multiple resonating structures.
