  • Publication number: 20150054711
    Abstract: Embodiments are provided for an efficient antenna design and operation method to adjust or add frequency bands at mobile devices using the available limited antenna size. The embodiments include electrically coupling to the antenna elements at a mobile or radio device a tuning stub or element through a printed circuit board (PCB) or a metal chassis. The PCB is placed between the antenna elements and the tuning stub and is connected to the antenna elements. The tuning stub, e.g., at a corner of the PCB, is connected or disconnected via a switch from the PCB, and hence the antenna elements, to shift the radiation of the antenna at different frequencies and also provide an additional mode of radiation. The tuning stub can also be switched to vary the radiation pattern of the antenna.

  • Patent number: 8947308
    Abstract: A system that incorporates the subject disclosure may include, for example, a method for coupling a primary antenna to an auxiliary antenna portion with a current-controlled switch. The method further includes generating a unidirectional direct current or a first bias voltage having a first polarity to cause the current-controlled switch to substantially form a conduction channel between the primary antenna and the auxiliary antenna portion. While the conduction channel is present, a first resonance frequency range of the primary antenna is frequency shifted to a second resonance frequency range. The method can also include removing the unidirectional direct current or generating a second bias voltage having a second polarity to cause the current-controlled switch to form an open circuit between the primary antenna and the auxiliary antenna portion. While the open circuit is present, the first resonance frequency range of the primary antenna is restored. Other embodiments are disclosed.

    Abstract: In some embodiments, an apparatus comprises of a ground plane control module included in an antenna system having a set of antenna segments that includes a first antenna segment, a second antenna segment, and a third antenna segment, with each antenna segment associated with a separate ground plane. The ground plane control module is configured to selectively activate the ground plane of the first antenna segment and the second antenna segment such that receive signals and transmit signals are communicated with a first and second user, respectively, when the ground planes of the first and second antenna segments, respectively, are in an activate mode. The ground plane control module is configured to selectively activate the ground plane of the third antenna segment such that the third antenna segment cannot communicate receive signals and transmit signals when the ground plane of the third antenna segment is in a deactivate mode.

  • Patent number: 8928541
    Abstract: An active antenna system and algorithm is proposed that provides for dynamic tuning and optimization of antenna system parameters for a MIMO system that will provide for greater throughput. As one or multiple antennas are loaded or de-tuned due to environmental changes, corrections to correlation and/or isolation are made by tuning the active antenna. A null-steering technique is implemented to alter the near-field and far-field characteristics to aid in modifying correlation and isolation in the multi-antenna system.
