    Abstract: A method for testing remote transponders. In the method, a radio-frequency transponder is excited by sending an excitation command having a minimum threshold transmission power with the aid of a first electromagnetic field and the response of the radio-frequency transponder to the excitation command is measured with the aid of a second electromagnetic field in order to test if a corresponding received power threshold is exceeded. One of the fields is a radiating field and the other of the fields is a reactive field. The need to test transponders separately from other transponders and the need to inactivate or screen other transponders in the vicinity of the transponder being measured is eliminated.

  • Patent number: 8878742
    Abstract: Embodiments in accordance with the invention include a linearly polarized dipole antenna with an unbalanced microstrip feed line. More specifically, embodiments in accordance with the invention utilize a fed dipole connected to a microstrip feed line, and separated a gap distance from a parasitic dipole not connected to the microstrip feed line. When an electrical signal is input to the microstrip feed line, the microstrip feed line creates a current flow in the fed dipole which induces a nearly equal current on the parasitic dipole that is out of phase. The result is a current flow, I, in the same direction in both fed and parasitic dipoles allowing for efficient radiation of the linearly polarized dipole antenna. Embodiments in accordance with the invention eliminate the need for a balun circuit thereby reducing the size, complexity and feed loss of the feed circuit. Embodiments in accordance with the invention are effective for dipoles with relatively small ground planes.

  • Patent number: 8847840
    Abstract: Techniques, devices and systems use pseudo-conductor materials as antennas to receive or radiate electromagnetic energy for communications and other applications. Methods of configuring an antenna can include, in some implementations, selecting a pseudo-conductor material having an electromagnetic constitutive property, wherein the electromagnetic constitutive property comprises a real part of the electromagnetic constitutive property that is greater than a corresponding imaginary part of the electromagnetic constitutive property; and forming the pseudo-conductor material into an antenna shape configured, upon being excited, to radiate emissions that satisfy a predefined antenna performance, such that the pseudo-conductor material formed in the antenna shape weakly guides an electromagnetic wave on the pseudo-conductor material using a leaky mode that is below cutoff to establish a field structure to radiate the emissions from the pseudo-conductor material that satisfy the antenna performance.

  • Patent number: 8810466
    Abstract: A wide-bandwidth antenna (e.g., a rib-dipole antenna) includes a first pole formed by a first conductive member and/or a second pole formed by a second conductive member. The antenna also includes an antenna feed between the first conductive member and the second conductive member. The antenna also includes at least one electrically conductive element including a surface. A portion of the surface is electrically connected to, and extends from, the first conductive member or the second conductive member. The at least one electrically conductive element is capable of conducting a current that generates a magnetic field. The magnetic field lowers a total reactance of the antenna, thereby resulting in enhanced performance of the antenna and more efficient use of volume.

  • Patent number: 8810465
    Abstract: A distributed comb tapped multiband antenna structure includes a PIFA-like antenna radiator having tap structures, and a counterpoise to the antenna radiator, wherein the tap structures include shunt connections to the counterpoise. A second antenna radiator is collinear and opposing the antenna radiator while sharing the counterpoise in common with the antenna radiator, such that the antenna structure is configured as a balanced dipole. The antenna structure can be contained internally within a single device housing and can operate over multiple frequency bands. The antenna provides high performance over a considerable bandwidth within each of the multiple frequency bands of operation, even where the frequency bands are not harmonically related.
