A low profile UWB vertical strip monocone antenna

Based on the principle of discone antenna a new UWB monocone antenna is presented. Instead of using traditional cone geometry as a radiator for discone, planar vertical strips of aluminum are used as an antenna radiator. This results in wide impedance characteristic and miniaturization of antenna. The simulated model has broadband impedance bandwidth 20:1 lform 550MHz to 20 GHz with Omni directional radiation pattern. The N type panel mount connector is used for antenna feeding. As result of a low profile, antenna can be easily mounted for portable application. The measured results of antenna are found to be in good agreement with simulation results.
