Abstract
An antenna is provided comprising a pair of driven elements and a pair of passive elements. The driven elements are disposed on opposite sides of a reference plane, and the passive elements are also disposed on opposite sides of the reference plane. One or both passive elements may be provided in a different plane than the driven elements. By varying placement of the passive elements the antenna radiation pattern can be altered. An antenna array is also provided, comprising two or more oppositely directed directional antennas at least one of which is as described above. The passive elements of the antennas can be adjusted for a desired coverage pattern of the array, such as an azimuthal omnidirectional pattern, for example through simulation. The antenna or array may be embodied on a printed circuit board.
