Abstract
A compact, omnidirectional, broadband biconical antenna is described, having a first segment with its tip coincident with a horizontal plane, with an elevation angle between 23 degrees and 30 degrees from the horizontal plane; an open second segment joined to a distal end of the first segment, an elevation angle approximately 30 degrees greater than the first segment angle; an open third segment joined to a distal end of the open second segment, an elevation angle approximately 30 degrees greater than the open second segment angle; an open fourth resistive film segment joined to a distal end of the open third segment, an elevation angle approximately equal to the open third segment angle, wherein the segments are mirrored to form a biconical antenna; and a transmission line coupled to the tip of the first segment, interior to the first segment.
