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