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. Montgomery, Frank M. Caimi, Paul A. Tornatta, Mark W. Kishler, Li Chen

Publication number: 20140062819Abstract: 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: ApplicationFiled: August 23, 2013Publication date: March 6, 2014Applicant: SKYCROSS, INC.Inventors: Mark T.
