A Compact implementation of a microstrip monopole antenna for the future super wideband (SWB) communications is proposed. The proposed antenna possesses an excellent impedance bandwidth performance over a broad frequency range (3 to 33 GHz) with switchable dual band-notch characteristics. The notch bands were realized using bandstop resonators to reject lower and/or upper WLAN applications (5.15 to 5.35 GHz and 5.725 to 5.825 GHz, respectively). The proposed resonators with open circuit stubs allow operation at low frequencies while maintaining a compact size. Switching elements were incorporated into the design to provide the switching functionality of the notch bands. Full-wave EM simulations were performed for demonstrating the proposed antenna operation.
