Abstract

This paper presents a circular monopole UWB antenna, which has an approximately 30 times octave bandwidth constant group delay, acceptable gain flatness and high efficiency, and introduces the primary antenna design. In this paper, the theoretical analysis, simulation by CST Microwave Studio and experiments are all conducted to further characterize the antenna in terms of the influences on its performance by varying the dimension parameters of the antenna. Also, via the experiments, this paper originally presents the idea of improving the impedance bandwidth by modifying the structure of feeding network.
