Abstract:
1. A full-duplex antenna system for selectively tuning communication channels, the system comprising: a first antenna effectively resonant at a frequency selectable first channel in an first frequency band, having an interface port with a first impedance at the first channel frequency; a second antenna effectively resonant at a frequency selectable second channel in the first frequency band, having an interface with a second impedance at the second channel frequency; a first matching circuit including a port connected to the first antenna interface port having a first conjugate impedance at the first channel frequency; and, a second matching circuit including a port connected to the second antenna interface port having a second conjugate impedance at the second channel frequency.
