Creating multiple band notches in an extremely wideband printed monopole antenna

摘要

Three notched bands are generated, at selected frequencies, in an extremely wideband base antenna in order to support multiple communication systems while avoiding inference from other systems. Measurements confirm that the fully printed base antenna has an extremely wide 2:1 VSWR bandwidth from 0.72 GHz to more than 30 GHz. By introducing a tuning stub and a pair of open arc-shaped slots, three band notches are created to prevent interference from WLAN (2.5 GHz and 5 GHz) systems and some C-band satellite communication systems.
