Abstract: First, second and third feed ports interface to an antenna that has an impedance disposed between its ends which are defined by the first and second feed ports. The third feed port interfaces to the antenna at an intermediate point between the ends. In a first mode (balanced mode) the impedance enables signals to/from the first and second feed ports to resonate along the whole of the antenna, and in a second mode the impedance enables signals to/from the third feed port to resonate along a portion of the antenna, the portion terminating at the impedance. In embodiments, the first mode is for RFID signals and the second mode is for any one or more of Bluetooth/WLAN/GPS/FM signals. The first and second mode may operate simultaneously. Also detailed is a method for making an electronic device having such an antenna.

Abstract: An apparatus such as for example an antenna sub-assembly includes a multiband antenna circuitry and feed circuitry. The multiband antenna circuitry includes a resonator; a first ground port configured to couple the resonator to a common voltage potential; and at least one reactive component disposed between the resonator and the first ground port. The feed circuitry includes: a signal feed port configured to couple to a radio; a second ground port configured to couple the feed circuitry to the common voltage potential; and a feeding element disposed between the signal feed port and the second ground port, the feeding element configured to inductively couple the feed circuitry to the antenna circuitry between the resonator and the first ground port. In some example embodiments there is a variable reactance to enable the resonator to be tunable. In those and/or other embodiments there is a second and even a third resonator for multi-band operation.
