Patent number: 8803756Abstract: A multimode antenna structure is described for a communications device. The communications device includes circuitry for processing signals communicated to and from the antenna structure. The antenna structure is configured for optimal operation in a given frequency range. 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.Type: GrantFiled: August 23, 2013Date of Patent: August 12, 2014Assignee: Skycross, Inc.Inventors: Mark T.

Patent number: 8723743Abstract: A method is provided for reducing near-field radiation and specific absorption rate values in a communications device that includes a multimode antenna structure transmitting and receiving electromagnetic signals and circuitry for processing signals communicated to and from the antenna structure. The method includes adjusting the relative phase between signals fed to neighboring antenna ports of the antenna structure such that a signal fed to the one antenna port has a different phase than a signal fed to the neighboring antenna port to provide antenna pattern control and to increase gain in a selected direction toward a receive point. The method features using a transmit power lower than the transmit power used in a non-pattern control operation of the antenna structure such that the communications device obtains generally equivalent wireless link performance with the receive point using reduced transmit power compared to the non-pattern control operation, thereby reducing the specific absorption rate.Type: GrantFiled: December 26, 2012Date of Patent: May 13, 2014Assignee: Skycross, Inc.Inventors: Mark T.

Patent number: 8588717Abstract: A radio communications device includes a headphone assembly, which includes at least one aural speaker or transducer and a headphone cable functioning as an antenna and providing electrical signals carrying audio information to the at least one aural speaker or transducer. A signal separator coupled to the headphone cable separates the electrical signals carrying audio information transmitted to the headphone cable and radio frequency (RF) signals received from the headphone cable. A radio receiver receives the RF signals from the signal separator and converts the RF signals to electrical signals carrying audio information. A tuner is provided for tuning the headphone cable to a selected operating frequency of the radio receiver. An audio amplifier amplifies electrical signals carrying audio information from the radio receiver to be transmitted through the headphone cable to the at least one aural speaker or transducer.Type: GrantFiled: December 27, 2011Date of Patent: November 19, 2013Assignee: Skycross, Inc.Inventor: Frank M.

Publication number: 20130229316Abstract: 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.Type: ApplicationFiled: February 15, 2013Publication date: September 5, 2013Applicant: Skycross, Inc.Inventors: Li Chen, Frank M. Caimi, Mark T. Montgomery, Paul A.
