摘要：
The main motive of this paper is to discuss design and performance analysis of a modified circular planar monopole UWB antenna. The proposed antenna, printed on a FR-4 substrate of dimensions 30mmx2Ommx1.6mm, is designed to operate within the 2.66GHz to 11GHz band that includes the FCC unlicensed spectrum of 3.1GHz to 10.6GHz. It attains a highest peak gain of 3.157dBi at 10GHz and a maximum radiation efficiency of 96.6% at 3.1GHz. This paper initially presents a conventional circular planar monopole UWB antenna design and then discusses a systematic optimization process to achieve the proposed UWB antenna from the conventional UWB antenna. In this process affects of various slots on the return loss performance are also studied. Then, it reports proposed antenna group delay performance and a comparative performance analysis of the two UWB antennas. Finally, the proposed UWB antenna structure is fabricated and verified. The measurement shows a good agreement with the simulated result.
