Abstract: A quick solder chip connector is provided that can include a body, a radio signal conductor housed in the body, and one or more grounding pins integrally formed in the body. In some embodiments, the radio signal conductor can include a first end configured to electrically connect to a first transmission line formed on a first printed circuit board and a second end configured to electrically connect to a second transmission line formed on a second printed circuit board and can provide a radio frequency signal path between the first transmission line and the second transmission line. The one or more grounding pins can extend from opposing ends of the body and can be configured to physically support the body and the radio signal conductor between the first printed circuit board and the second printed circuit board.

Abstract: An antenna system that can reduce signal radiation in an unwanted direction while preserving signal radiation outside of the unwanted direction is provided. The antenna system can include a signal input source with a main antenna and a secondary antenna each electrically coupled to the signal input source. The main antenna can transmit a primary signal to produce a primary radiation pattern in response to a first portion of energy from the signal input source, and the secondary antenna can transmit a secondary signal to produce a secondary radiation pattern in response to a second portion of energy from the signal input source. The secondary signal can be amplitude modified and phase shifted to position the secondary radiation pattern to cancel out or reduce a portion of the primary radiation pattern extending in an unwanted direction while substantially preserving portions of the primary radiation pattern outside of the unwanted direction.

Abstract: A method for adjusting a graphical user interface on an electronic device includes receiving, from a detection element positioned at a backside of an electronic device, first data generated when a hand is positioned at the backside of the electronic device. Further, a one-handed or two-handed operation of the electronic device is determined based on the first data. A displaying of a graphical user interface on the electronic device is adjusted when the one-handed operation is determined.

Abstract: A wireless device (102) having a slot antenna (104) is disclosed. The slot antenna includes at least one conducting element. Examples of the at least one conducting element include a Printed Circuit Board (PCB) ground, a metallized battery housing, a metallized frame of a display screen, a metallized housing of a keypad frame, and a metallized housing of the wireless device.

Abstract: A material properties detection system (100). The system can include an antenna (120) that is tuned for operation within a frequency band over which the antenna transmits. The system also can include a transmitter (210) that generates electromagnetic energy across the frequency band and forwards the electromagnetic energy to the antenna. An impedance measurement circuit (215) can be provided. The impedance measurement circuit can measure an input impedance of the antenna over the frequency band and generate measured impedance data (225). The system can include a material characterization application (230) that processes the measured impedance data to generate a material characterization for a structure (110) to which the antenna is proximate. The material characterization can include a dielectric constant, a permittivity, a loss tangent and/or a permeability.

Abstract: A multiple band antenna has an RF coupling structure (110) and a resonant RF structure (102). The RF coupling structure (110) has an RF connection (116, 118) and an RF coupling end (112, 114). The resonant RF structure (102) is reactively coupled to the RF coupling end (112, 114). The resonant RF structure (102) has a first end (106) and a second end (108) and has a conductive perimeter (102) enclosing at least one slot area (104) configured to induce an additional resonant RF band for the resonant RF structure (102). The first end (106) and the second end (108) are reactively coupled to a ground plane (124, 120) to facilitate longer wavelength operation. Cellular phones (800) and wireless communications sections incorporating such antennas are also provided.

Abstract: An antenna structure incorporating a unitary radiator including a compression housing. The compression housing snap fits to a ferrule to compress the unitary radiator to ensure electrical contact between the unitary radiator and an electrical contact, such as the ferrule. Upon assembly, the compression housing is snap fit to the ferrule to compress the radiator. Preferably, to accommodate snap fit construction, an end of the ferrule includes at least one detent that corresponds to at least one projection on the compression housing. Another end of the ferrule preferably includes at least one projection that corresponds to at least one detent on the portable communicator to achieve a snap fit between the ferrule and the portable communicator. To accommodate two bands, the unitary radiator preferably has a generally helical shape formed by an outer portion thereof and a center portion disposed within the outer portion.
