摘要： An adaptive antenna system having a counterpoise conductor contained within a housing of a communication device and located distally from such surfaces of the housing that can be held by or placed in proximity to a user or external objects which detune the counterpoise. A tuning circuit is coupled between the counterpoise conductor and a ground. The tuning circuit is operable to adapt the resonant frequency of the counterpoise conductor to divert operational RF currents away from the ground located in proximity the user or external objects and onto the counterpoise conductor.

摘要： A multi-function antenna system for a radio communication device includes a housing that encloses a radio frequency transceiver of the radio communication device. A mounting base is coupled to the housing and has a first set of electrical contacts coupled to the transceiver. An antenna element is coupled by a hinge to the mounting base and has a second set of electrical contacts. Different portions of the first and second set of contacts are connectable as a function of the relative positions of the mounting base and the antenna element so as to provide different antenna functions.

摘要： An improved antenna system to channel counterpoise currents for an unbalanced antenna such as a helical monopole. A first conductor, or ground resonator, is coupled to a ground connection near the antenna and is located distally from a user to reduce electromagnetic exposure. The first conductor presents a low impedance path at an operating frequency of the antenna such that RF currents are attracted onto the first conductor. A second conductor, such as a printed circuit board or user interface circuitry, is also coupled to the ground connection of the first conductor. The second conductor presents a high impedance path at the operating frequency of the antenna such that RF currents are diverted away from the second conductor which is held closer to a user than the first conductor.

摘要： An electronic device (100) includes an antenna system (150) having two antennas (110, 120). A first antenna (110) has a first antenna element (111) positioned outside a first corner (191) of a planar, rectangular ground plane (165) and a second antenna element (115) positioned outside a second corner of the ground plane that is diagonally across from the first corner. A second antenna (120) has a third antenna element (121) positioned near a third corner (193) of the ground plane that is adjacent to the first corner and a fourth antenna element (125) positioned near a fourth corner (195) of the ground plane that is diagonally across from the third corner. At low-band frequencies, the antenna elements (111, 115) of the first antenna (110) are driven out-of-phase relative to each other. Similarly, at low-band frequencies, the antenna elements (121, 125) of the second antenna (120) are driven out-of-phase relative to each other.

摘要： An energy density diversity antenna (EDA) has a least a pair of antenna elements, whose feeding points are connected to outputs of a hybrid coupler configured such that a sum and a difference signal may exist at the feed points of the antenna elements. First reactive elements are respectively inserted in the antenna elements proximal the respective feed points. The antenna elements are joined at a point distal from the feed points by a second reactive element, and a third reactive element is coupled between feed lines coupled to the feed points at a location between the feed points and the outputs of the hybrid coupler.
