A novel super-wideband (SWB) antenna is presented. It is designed in microstrip technology based on planar monopole antenna theory. In order to achieve acceptable high-frequency return loss, a gap is added between the radiator and the ground plane, and the microstrip line is narrowed down at the feeding point. The prototype is fabricated on standard Rogers 5880 substrate with thickness of 0.254 mm and εr = 2.2. Measurements of the return loss up to 110 GHz and measured patterns and gain up to 40 GHz show good agreement with results from full-wave simulations.
