Abstract

In order to improve the practicability and versatility of ultra-wideband (UWB) antennas, a reconfigurable band notch antenna is proposed in this paper. It has a compact size of 18 mm×16 mm×1.6 mm. The reconfigurable band notch function is realized by two small tunable units. The tunable unit makes up of a split ring resonator (SRR), a dielectric substrate, and a varactor diode. The simulation results show that the antenna combines the functions of band notch emergence, removal and movement. The applied reconfigurable method can effectively broaden the continuous movement range of band notch. The measurement proves that the antenna has the band notch reconfigurable function, and the measured results are in good agreement with the simulation ones. The radiation patterns are measured, which are stable and consistent under two modes with and without band notch, showing omnidirectional radiation characteristics. These research results provide reference value for the design of band notch UWB antenna shielding civil narrowband communication band.
