Abstract

An electronic device using arbitrary transmit polarizations is described. The electronic device includes a first antenna having a first predefined polarization and a second antenna having a second predefined polarization, where the second predefined polarization is different from the first predefined polarization. During operation, an interface circuit in the electronic device selectively transmits a first wireless signal corresponding to a packet or frame from the first antenna. In addition, the interface circuit selectively transmits a second wireless signal corresponding to the packet or frame from the second antenna, where the second wireless signal has the same magnitude as the first wireless signal and the second wireless signal is transmitted from the second antenna in parallel with (or simultaneously with) the first wireless signal being transmitted from the first antenna. Note that the interface circuit can dynamically modify the transmit polarization during communication.
