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: 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: 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.
