Antenna systems with both single-ended and differential signal feeds

An antenna system for a mobile device, the antenna system comprising:

• a first plurality of signal conditioning circuits including a first radio frequency signal conditioning circuit configured to condition a first radio frequency signal that is single-ended and of a first frequency, the first plurality of signal conditioning circuits configured to provide beamforming on the first frequency;
• a second plurality of signal conditioning circuits including a second radio frequency signal conditioning circuit configured to condition a second radio frequency signal that is differential and of a second frequency, the second plurality of signal conditioning circuits configured to provide beamforming on the second frequency;
• and
• an antenna array that includes an antenna including a first signal feed connected to the first radio frequency signal conditioning circuit and a pair of second signal feeds connected to the second radio frequency signal conditioning circuit.

A method of wireless communication in a mobile device, the method comprising:

• conditioning a first radio frequency signal that is single-ended and of a first frequency using a first radio frequency signal conditioning circuit of a first plurality of signal conditioning circuits;
• conditioning a second radio frequency signal that is differential and of a second frequency using a second radio frequency signal conditioning circuit of a second plurality of signal conditioning circuits;
• providing beamforming on the first frequency using the first plurality of signal conditioning circuits;
• providing beamforming on the second frequency using the second plurality of signal conditioning circuits;
• handling the first radio frequency signal using a first signal feed of an antenna of an antenna array;
• and
• handling the second radio frequency signal using a pair of second signal feeds of the antenna.
