Abstract

The proposed antenna is a small ultra-wideband antenna with an omni-directional pattern in the azimuth plane and with two lobes tilted several degrees from the horizon in the elevation plane. The antenna is a biconical antenna consisting of two cones in which the differences in their diameter determine the tilt of the pattern. The antenna has a unique shape, having a half sphere placed above the top cone´s base. A frequency band of two octaves was realized. Simulations and measurements were performed by locating the antenna above a flat finite ground plane. There was a good match between the simulations and the measurements. Further work will be done to determine the effect of a radome on the antenna´s performance.
