| 20090051611 | ANTENNA WITH ACTIVE ELEMENTS - A multi-frequency antenna comprising an IMD element, active tuning elements and parasitic elements. The IMD element is used in combination with the active tuning and parasitic elements for enabling a variable frequency at which the antenna operates, wherein, when excited, the parasitic elements may couple with the IMD element to change an operating characteristic of the IMD element. | 02-26-2009 |

| 20100259457 | MULTI-FREQUENCY, NOISE OPTIMIZED ACTIVE ANTENNA - A multi-frequency, noise optimized active antenna consisting of one or several actively tuned antennas optimized over incremental bandwidths and capable of tuning over a large total bandwidth. One or multiple impedance transformers are connected to the antennas at an optimal location, with the transformers acting to reduce the impedance for optimal coupling to a transceiver/receiver.

The radiating elements can be co-located with a ferrite material and/or active components coupled to the element to tune across a wide frequency range. | 10-14-2010 |
| 20120026049 | MULTIBAND DISMOUNT ANTENNA - Antennas and methods for controlling antennas for producing electromagnetic radiation in a desired direction over a wide range of wavelengths. A current distribution is controlled in one or more conductive radiating elements of an antenna to form, at every wavelength within a pattern wavelength range, an antenna radiation pattern having a peak in a direction substantially orthogonal to a length of an elongated conductive radiating element or elements. By careful control of the current distribution, the pattern wavelength range is made exceptionally broad. In the case of a dipole antenna, the pattern wavelength can range from about ⅓l to at least about 8l, where l is an approximate combined length of a pair of elongated elements forming a dipole antenna. Alternatively, in the case of a monopole antenna, the pattern wavelength range can extend from about ⅙l to at least about 4l, where l is an approximate overall length of the monopole antenna. | 02-02-2012 |

A magnetic dipole mode is generated by coupling a driven element to a second element, and additional resonances are generated by coupling additional elements to either or both of the driven or second element. One or multiple active components can be coupled to one or more of the coupled elements to provide dynamic tuning of the coupled or driven elements. | 10-03-2013 |

The antenna structure includes a plurality of antenna ports operatively coupled to the circuitry, and a plurality of antenna elements, each operatively coupled to a different one of the antenna ports. Each of the plurality of antenna elements is configured to have an electrical length selected to provide optimal operation within the given frequency range. By way of one or more connecting elements, electrical currents on one antenna element flow to a connected neighboring antenna element and generally bypass the antenna port coupled to the neighboring antenna element. | 03-06-2014 |
