Abstract
An embodiment of an antenna module includes a substrate, a first antenna, and a second antenna. The first antenna is disposed on the substrate and is configured to radiate a first signal having a wavelength and a first polarization. And the second antenna is disposed on the substrate and is configured to radiate a second signal having the wavelength and a second polarization that is approximately orthogonal to the first polarization. For example, such an antenna module can include, as the first antenna, a T antenna configured to transmit and receive data that forms a first part of a MIMO-OFDM data symbol, and can include, as the second antenna, an F antenna configured to transmit and receive data that forms a second part of the MIMO-OFDM data symbol.
