Abstract: An antenna coupler (100) for use in a mobile adaptor (102, 300) transfers radio frequency (RF) energy between a portable radio antenna system (204) and an external antenna (124) with minimal coupling losses. The antenna coupler (100) includes a resonator patch (110) and an electromagnetic tuning element (112) forming side walls on a substrate for receiving the portable antenna system (204). The electromagnetic tuning element (112) controls the impedance between the resonator patch (110) and the portable antenna system (204) while the resonator patch transfers the RF energy between the portable radio antenna and the external antenna (124).
