Two-Step Beveled UWB Printed Monopole Antenna with Band Notch

Abstract EN

This paper presents a novel compact printed monopole ultra-wideband (UWB) antenna featured with the band notch.

The proposed antenna consists of a two-step beveled radiant patch and a truncated ground plane, which can provide a good impedance matching from 3.1 GHz to 10.6 GHz.

In order to generate the band-notched characteristics, two symmetrical slots are embedded along with the microstrip feeding line, resulting in a band notch from 5.05 GHz to 5.85 GHz.

Accordingly, the mutual electromagnetic interference between the UWB and wireless local area network (WLAN) radio communication systems can be eliminated.

In addition, it is shown how the slots integrated on the ground plane improve the radiation patterns.

The experimental measurements are found to be in good agreement with the numerical simulations.
