1. An antenna apparatus for use in a wireless communication subscriber unit, comprising:
- at least two passive antenna elements and one active antenna element;
the passive antenna elements being positioned about the active antenna, such that the passive elements are not located in at least one common plane with the active element, and such that each of the at least two passive antenna elements are individually setable to a reflective or a transmissive mode to change the characteristics of an input/output beam pattern of the antenna apparatus; and
a respective resonant strip positioned beneath each passive antenna, the combination of each passive antenna element with a respective resonant strip providing an unbalanced dipole antenna element so that the multiplicity of dipole antenna elements form a composite input/output directed beam which may be directed along a horizon.

Abstract
An antenna array that uses at least two passive antennas and one active antenna disposed above a ground plane, but electrically isolated from the ground plane, and a respective resonant strip positioned beneath each passive antenna. The passive antenna elements are positioned about the active element, and each of the at least two passive antenna elements is individually set to a reflective or a transmissive mode to change the characteristics of an input/output beam pattern of the antenna apparatus.
