Abstract

This paper presents a wideband conical antenna incorporating a band-notched resonator. The notch band is created by using four U-shaped slots which are cut into the surface of the elliptical cone antenna. The notch band is located at 5 GHz. In comparison with previous work the main advantages of this contribution include 1) the simplicity with which the position of the notch band can be adjusted by altering the size of slot, 2) the high quality factor (high Q associated with the notch band, 3) low level of insertion loss at the centre of the notch band, and 4) omni-directiona pattern at frequencies throughout the operating band.
