Abstract
An ultra-wideband tapered slot antenna that is capable of providing spatial independent band-stop characteristics which are irrelevant to the radiation direction of the antenna in a dual-stop band. The antenna includes an ultra-wideband tapered slot antenna includes a radiating unit formed on a first surface of a substrate and configured to radiate radio signals. A feeding unit is formed on a second surface of the substrate and is configured to provide the radio signals to the radiating unit. Separate stubs are formed to be spaced apart from the feeding unit around the feeding unit and are configured to reject frequencies in a first stop band from the radio signals radiated from the radiating unit. A slot is formed in a stub formed at a first end of the feeding unit and is configured to reject frequencies in a second stop band from the radio signals.
