Title: Steerable-beam multiple-feed dielectric resonator antenna of various cross-sections
Inventor: KINGSLEY SIMON PHILIP
IPC: H01Q21/20
Filed: 2000-07-14
Granted: 2004-06-30
Abstract: A radiating antenna capable of generating or receiving radiation using a plurality of feeds and a dielectric resonator is disclosed. The purpose of using multiple feeds with a single dielectric resonator antenna is to produce several beams each having a 'boresight' (that is, a direction of maximum radiation on transmit, or a direction of maximum sensitivity on receive) in a different direction. Several such beams may be excited simultaneously to form a new beam in any arbitrary direction. The new beam may be incrementally or continuously steerable and may be steered through a complete 360 degree circle. The invention may be combined with an internal or external monopole antenna so as to cancel out the antenna backlobe or otherwise resolve the front/back ambiguity that arises with this type of dielectric resonance antenna. When receiving radio signals, electronic processing of such multiple beams may be used to find the direction of those signals thus forming the basis of a radio direction finding device. Further, by forming a transmitting beam or resolving a receiving beam in the direction of the incoming radio signal, a 'smart' or 'intelligent' antenna may be constructed. The excitation of several beams together can, in some combinations, produce a system with a significantly greater bandwidth than a beam formed by exciting a single probe or aperture. The dielectric resonator is mounted on a ground plane, is preferably substantially cylindrical, and is fed, for example, by a number of internal probes or external ground plane apertures. An internal or external monopole antenna may be added to improve performance.

Filed: 2006-09-05
Granted: 2008-08-13
Abstract: A sensor for condition monitoring the high voltage insulation of an electrical, generation, transmission or distribution system and/or an item of plant is described. The sensor comprises an impedance measurement unit that connects directly, via a single point of connection, to the electrical system to be tested. The electrical components of the impedance measurement unit are arranged so that high frequency partial discharge signals and low frequency power cycle information signal are preferentially transmitted through separate branches. Analysis of these separated signals thus enables extraction of information about the insulation of the electrical system being monitored. Safe operation of the sensor for users is also achieved through an opto-electronic circuit being employed to control the impedance measuring unit.
