Antenna ground and feed swapping in handheld applications

An apparatus, comprising:

• a casing having a first distal end, a second distal end opposite the first distal end, a first side, and a second side opposite the first side, the first side and the second side disposed between the first distal end and the second distal end;
• one or more antennas disposed adjacent the first distal end of the casing;
• a first feeding port adjacent the first distal end of the casing;
• a second feeding port adjacent the first distal end of the casing;
• one or more first shorting ports adjacent the first distal end of the casing;
• one or more second shorting ports adjacent the first distal end of the casing;
• and
• a control circuit communicatively coupled to the one or more antennas and configured to perform operations comprising:
• detecting a condition with respect to wireless communication through the one or more antennas to determine whether to operate in a first mode of wireless communication or in a second mode of wireless communication;
• in response to a determination to operate in the first mode, electrically connecting the first feeding port and the one or more first shorting ports to at least one antenna of the one or more antennas;
• and
• in response to a determination to operate in the second mode, electrically connecting the second feeding port and the one or more second shorting ports to the at least one antenna of the one or more antennas,
• wherein the at least one antenna has a symmetric antenna structure with a first slot toward the first side of the casing and a second slot toward the second side of the casing,
• wherein the first slot is associated with the first feeding port and the one or more first shorting ports such that the first slot, the first feeding port and the one or more first shorting ports are utilized in the first mode, and
• wherein the second slot is associated with the second feeding port and the one or more second shorting ports such that the second slot, the second feeding port and the one or more second shorting ports are utilized in the second mode.
