A diversity antenna exhibits a diversity gain pattern. The diversity gain pattern is provided as a combination of the gain patterns of first and second antennas. The first antenna has a ground plane that is disposed orthogonally with respect to the ground plane of the second antenna. In one arrangement of the invention, the first and second antennas are printed inverted F antenna structures, and may be disposed on a common circuit board substrate. The invention includes a device that incorporates the diversity gain antenna and may be disposed in a wireless local area network device. A diversity switch and a transmit and receive switch are provided to couple the diversity antenna to a baseband transceiver. The device may optionally include a processor to couple with the baseband transceiver, and may optionally couple with a host processor disposed in a host device to operate with the device having a diversity antenna in accordance with the invention.
