A dual autodiplexing antenna ( 300 ) redirects power flow ( 303 ) from an unloaded antenna to a loaded antenna, thereby improving communication performance under loaded conditions. The dual autodiplexing antenna ( 300 ) includes a first antenna ( 101 ) disposed at a first end ( 103 ) of a portable two-way communication device ( 100 ). A second antenna ( 102 ) is disposed at the distal end ( 104 ) of the portable two-way communication device ( 100 ). The first antenna ( 101 ) and second antenna ( 102 ) are coupled to a transceiver ( 107 ) by a first transmission line matching circuit ( 201 ) and a second transmission line matching circuit ( 202 ), respectively. In one embodiment, the first antenna ( 101 ) is configured to primarily operate in a first bandwidth, while the second antenna ( 102 ) is configured to primarily operate in a second bandwidth. When one of the first antenna ( 101 ) or second antenna ( 102 ) is loaded, power flow ( 303 ) is redirected to the lesser loaded antenna.
