Antenna method and apparatus

An apparatus comprising:

• an antenna having at least two signal inputs/outputs;
• a digital processing platform having an input operably coupled to the at least two signal inputs/outputs, wherein the digital processing platform has at least a first mode of operation comprising:
• summing a first signal that corresponds to energy received at a first part of the antenna with a second signal that corresponds to energy received at a second part of the antenna, wherein the second part is at least partially different than the first part, to provide a summed signal;
• determining a difference between the first signal and the second signal to provide a difference signal.

A wireless communication device comprising:

• antenna means for at least one of receiving and transmitting a wireless signal;
• digital cross-coupled sum and difference means operably coupled to the antenna means for at least one of:
• summing a first signal that corresponds to energy received at a first part of the antenna means with a second signal that corresponds to energy received at a second part of the antenna means, wherein the second part is at least partially different than the first part, to provide a summed signal;
• determining a difference between the first signal and the second signal to provide a difference signal;
• and
• summing a first outgoing payload signal with a second outgoing payload signal to provide a summed signal and providing the summed signal to be transmitted from a first part of the antenna means;
• determining a difference between the first outgoing payload signal and the second outgoing payload signal to provide a difference signal to be transmitted from a second part of the antenna means, which second part is different from the first part.
