Abstract
A terminal is provided for selectively communicating in at least two frequency bands. The terminal includes an antenna transducer including a first port and a second port, where the antenna transducer is capable of selectively transducing first radio signals (e.g., low power radio frequency (LPRF) signals) to and/or from the first port, and/or second radio signals (e.g., global positioning system (GPS) signals) to and/or from the second port. In this regard, the antenna transducer is capable of transducing first radio signals such that an impedance at the second port approaches a short circuit or an open circuit, and capable of transducing second radio signals such that an impedance at the first port approaches an open circuit. An associated communication assembly and method for selectively communicating in at least two frequency bands are also provided.
