Abstract
A monopole antenna is mounted on a ground plane and incorporates a radiating structure in the form of a blade perpendicular to the ground plane, for loading the antenna. An elevated feed is formed by a biconical central post between the blade and the ground plane. Tuning is also accomplished by a capacitive strips spanning the biconical central post and by outboard inductive posts which connect between the ground plane and the blade to provide shunt inductance. Alternatively, additional tuning may be accomplished by a circuit between upper and lower portions of the central post.
