摘要: There are first and second antennas proximally disposed configured to resonate within respective frequency bands, which may overlap. An impedance stabilization circuitry is coupled ground. a selective coupler (for example, diplexer, directional coupler, switch) interfacing the antenna selectively with radio circuitry. The comprises port antenna, circuitry, third couple that operate in band. provides predetermined signals band low insertion loss band, thus providing stable for antenna's view of antenna.
