Disclosed is a high performance, low cost antenna for wireless communication applications which benefit from a dual feed diversity antenna. The antenna device can be fabricated from a single layer of conductive material, thus allowing easy, low cost manufacture of a high gain antenna. Antenna embodiments may provide both spatial and polarization diversity. The antenna need not be planar, but rather may be bent or formed, such as to provide an antenna which is conformal with the shape of a wireless communication device. Furthermore, other embodiments of the present invention may be made of thin film, conductive foil, vapor deposition, or could be made of a flexible conductive material, such as metallized MYLAR. Each of the slot elements may be linear or may be formed in a meander shape or other shape to reduce size. The slot elements may be provided within an antenna array useful for beam scanning applications.

Diversity slot antenna

A dual frequency wideband antenna assembly for use in a wireless communication device. The antenna assembly having a first resonator element disposed away from the ground plane element, said first resonator element being operatively coupled at a first location to the ground plane and being operatively coupled at a second location to the RF signal port; a second resonator element disposed away from the ground plane. The first and second resonator elements are coupled via a bridge conductor and a capacitive tuning network. The capacitive tuning network may include a discrete capacitor or an adjustable capacitor which varies in response to a signal.
