Diversity gain antenna
First Claim
1. An apparatus, comprising:
- a first antenna having a ground plane; and
a second antenna having a ground plane;
the first and second antennas being disposed with respect to one another wherein the ground plane of the first antenna and the ground plane of the second antenna each are disposed orthogonally with respect to each other to provide complementary gain patterns combined into an overall diversity gain pattern.

Abstract
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.
