Abstract

A novel electric small conical antenna working on a very broad band, 0.47-6 GHz, with the height of only 60 mm, is presented. A capacitive ring on the top of the cone and three oblique shorted lines are used to expanding the work band. By changing the width of the ring and the slope of the oblique line, the impedance of the antenna can be matched to 50-ohm feed line commendably. Simulations and experiments results demonstrate that this antenna provides very broadband and low-profile characters, which exhibits a 12.8:1 impedance bandwidth with voltage standing wave ratio (VSWR) below 2:1 (the impedance bandwidth is 11.9:1 with the VSWR below 1.5:1) and with the height only 0.094 wavelength associated to the lowest frequency.
