Abstract
A biconical antenna driven by an equal-delay transformer is provided herein with a bifurcating ground plane. According to one embodiment, the biconical antenna comprises a pair of cone-shaped elements and a conducting ground plate. The cone-shaped elements are arranged back-to-back to one another and aligned along a first axis. The conducting ground plate is arranged between the cone-shaped elements in a plane perpendicular to the first axis. As described herein, the bifurcating ground plane provides the decoupling needed to eliminate the anomalous undulations, which tend to occur in the antenna response at odd-integer average quarter-wave frequencies.
