Abstract
A bicone antenna is provided with high bandwidth and beneficial return loss performance. The antenna is dipole based and thus its radiation pattern is not strongly influenced by shape and size of a nearby ground plane. A parasitic element comprising a conductive band encircling the antenna's feed structure improves matching, gain flatness, and makes the antenna less susceptible to detuning.
