Abstract: A system for providing positioning functionality in an apparatus without having to implement dedicated hardware. An apparatus that desires to receive directional information may receive a message from another apparatus (e.g., access point or AP). The AP may operate in various modes that, for example, may provide directional information to other apparatuses as part of a general broadcast (e.g., a wireless local area network, or WLAN, beacon signal) or in response to messages requesting directional information that are received from other apparatuses. After receiving the message from the AP, the apparatus may determine if the message comprises directional information. If the message is determined to comprise directional information, directional information from the received message may be utilized to determine apparatus location. Otherwise, the apparatus may then send a message requesting directional information to the AP, which may prompt the AP to provide directional information.

Abstract: Provided herein is a compact and economical direction finding antenna using a mono-pulse antenna system, where a plurality of antenna elements are disposed in a circular array. The directional antennas may be formed by any type of antenna element, including a patch or reflector. The antenna beams of the directional antenna elements overlap, so that from any azimuthal direction, the point is covered by more than one antenna beam. Signals from each pair of adjacent antenna elements of the circular array are processed in order to determine the angle of arrival of a received signal.

Abstract: A radio direction finding antenna is disclosed. A dielectric material is configured to rotate about an axis of rotation. The dielectric material has a first conductive surface. A radiating element or array of radiating elements are disposed within the dielectric material and are electrically isolated from the first conductive surface. The radiating element or array of radiating elements are positioned a distance away from the axis of rotation and are configured to be resonant at a predetermined frequency in the case of a single radiating element or various frequencies in the case of an array of radiating elements. Rotation of the dielectric material and radiating element or array of elements about the axis of rotation causes a Doppler effect in signals received by the radiating element or array of elements.

Abstract: Substantial improvements in frequency reuse in microwave communications systems is achieved by canceling co-channel interference and transmitter leakage. Interferometric beam-narrowing reduces beamwidth without reducing peak magnitude of the beam pattern. Frequency-dependent beam-shaping compensates for frequency-dependent distortions of the beam pattern thereby improving bandwidth. A spatial demultiplexing technique utilizes spatial gain distributions of received signals to separate signals, even from co-located transmit sources, and uses microwave lensing to enhance received spatial gain distributions. Predetermined cross-polarization interference is used to separate differently-polarized receive signals. A reference branch provides a cancellation signal to a receiver to cancel transmitter leakage signals. An error signal controls an impedance-compensation circuit that is responsive to changes in antenna impedance but not to receive signals. A dc bias magnetic field applied to a magnetic permeable material adjusts non-linear distortion in a cancellation circuit for canceling distortion in a transmitter leakage signal. Discreet impedance elements approximate a circuit having distributed impedance.
