Abstract
The present invention is an adjustable beamwidth, loaded monopole antenna array. The array may include four monopole antennas. Each of the antennas may include a generally symmetric, tapered radiating element and an inductive shorting wall element. The array may further include a capacitive top hat element which may be connected to each of the antennas. The array may further include a ground plane element which may be connected to each of the antennas. The array may further include a plurality of feed posts which may be connected to the antennas. Further, each feed post may be connected to a power feed line. Each radiating element may be variably phase-fed and/or uniformly phase-fed for allowing the antenna array to effect a directional beam and/or an omni-directional beam.
