Abstract: An antenna system comprises a receive diversity antenna system and a configurable antenna arrangement. Incoming signals are received through the receive diversity antenna system and outgoing signals are transmitted through the configurable antenna arrangement. A controller generates control signals to adjust the configurable antenna arrangement to change the transmission performance characteristics of the configurable antenna arrangement. The configurable antenna arrangement may be a smart antenna, a plurality of antennas, or a configurable antenna where transmission characteristics change in response to control signals.

Abstract: An antenna for a radio communications device includes a ground plane and a conductor loop overlying the ground plane. A monopole extends off the ground plane, and the monopole and the conductor loop are coupled at a common feedpoint. In some embodiments, the conductor loop is rectangular. In further embodiments, the antenna may further include a helical element arranged coaxial with the monopole and coupled to the common feedpoint. The ground plane, the conductor loop, the monopole and the helical element may be configured to provide a desirable voltage standing wave ratio (VSWR) over a wide frequency range of frequencies used for cellular telephony, global positioning services, and ad hoc wireless networking. Radio communications devices incorporating such antennas are also described.

Abstract: A single-feedpoint multiband monopole antenna is provided with independent radiator elements. The antenna comprises a microstrip counterpoise coupler having a single-feedpoint interface, a first radiator interface, and a second radiator interface. A first microstrip radiator, i.e. a meander line microstrip, has an end connected to the counterpoise coupler first radiator interface, and an unterminated end. A second microstrip radiator, i.e. a straight-line microstrip, has an end connected to the counterpoise coupler second radiator interface, and an unterminated end. The two radiators are capable of resonating at non-harmonically related frequencies. As with the two microstrip radiators, the microstrip counterpoise coupler is a conductive trace formed overlying a sheet of dielectric material. The counterpoise coupler can come in a variety of shapes, so that the overall antenna may take on a number of form factors.

The transformer loop has a balanced feed interface and includes a side that provides a transformer interface of quasi loops formed by the plurality of magnetic dipole radiators. Each quasi loop has a configuration and length to maximize antenna performance within a different frequency band. The at least one capacitively-loaded magnetic dipole radiator may be formed with a meander line structure and may include an electric field bridge such as a dielectric gap, lumped element, circuit board surface-mounted, ferroelectric tunable, or a microelectromechanical system (MEMS) capacitor.

Abstract: A frequency-tunable capacitively-loaded magnetic dipole antenna includes a transformer loop having a balanced feed interface, and a capacitively-loaded magnetic dipole radiator with a tunable effective electrical length. In one embodiment, the capacitively-loaded magnetic dipole radiator includes a tunable electric field bridge. For example, the capacitively-loaded magnetic dipole radiator may comprise a quasi loop with a tunable electric field bridge interposed between the quasi loop first and second ends. The electric field bridge may be an element such as a ferroelectric (FE) tunable capacitor or a microelectromechanical system (MEMS) capacitor, to name a couple of examples. In certain embodiments, the capacitively-loaded magnetic dipole radiator includes a quasi loop with a loop perimeter. The effective electrical length of the radiator is changed by adjusting the perimeter using an element such as a MEMS switch, or a semiconductor switch.

Abstract: Multi-band, Inverted-F Antenna with capacitively created resonance, and radio terminal using same. The present invention creates an additional resonance frequency in a planar-style, inverted-F antenna (PIFA), such as that typically used in mobile radiotelephone or other types of radio terminals. A first radiating branch of the antenna is connected to the signal feed conductor and the ground feed conductor. A second radiating branch is connected to the signal feed conductor and the ground feed conductor at one end and is capacitively coupled to the first radiating branch at the other end so that the antenna resonates at an additional resonance frequency. The additional resonance frequency can be used for, among other things, adding GPS or Bluetooth functionality to a radiotelephone terminal that otherwise operates on GSM (Global System for Mobile) or other mobile radiotelephone terminal frequencies.

Abstract: Selectively engaged antenna matching for a mobile terminal. Antenna matching can be engaged, disengaged, or switched as needed depending on whether a movable cover or clam-shell portion of a mobile terminal is open or closed. A switch can connect a single matching network to a radiating element in one case, and disconnect the single matching network from the radiating element in the other case. Alternatively, the switch can connect one matching network to the radiating element to achieve one matched condition, and the other matching network to the radiating element to achieve the other matched condition. In other embodiments, a switchable matching arrangement can alter the signal and/or ground feed points of an antenna. The technique can be applied to planar, fixed external, or collapsible antennas.
