    摘要: At least one of the following requirements is satisfied. A position of a curvature center of an arcuate portion in at least one of waveguide plates is selected between a connecting member and a power feeder, in accordance with a desired horizontal beam radiation characteristic. A curvature radius of the arcuate portion in at least one of the waveguide plates is selected in accordance with a desired vertical beam radiation characteristic. A slanted angle of a peripheral face of the arcuate portion, which connects a top face and a bottom face of each waveguide plate, in at least one of the waveguide plates is selected in accordance with a desired vertical beam radiation characteristic.

    摘要: A parabolic rectangular horn antenna includes a source aperture, a parabolic reflector, and an output aperture. The source aperture has a first port for receiving a planar wavefront signal and a second port for providing a substantially cylindrical wavefront signal. The parabolic reflector is positioned within the horn to receive the cylindrical wavefront signal, transforming it to a substantially planar wavefront signal at a predefined location. The output aperture is positioned at the predefined location and outputs the substantially planar wavefront signal. Corrugations are adjacently placed at both sides of the output aperture to optimize the antenna beam pattern.

    摘要: A multilayer antenna is provided, which includes a power supply portion generating a wave, a radiating portion, and a guide portion that makes it possible to guide the wave from the power supply portion to the radiating portion. The guide portion includes: at least two stacked guide layers having parallel planes and, for each pair of adjacent layers, a transition between the adjacent layers, including a reflector engaging with a slot-coupling. For at least one pair of adjacent layers, for which the guide portion includes a non-planar reflector, the slot-coupling includes a plurality of slots. Each slot includes a main body that is elongate along at least one axis. The slots are placed on at least one row and together form a pattern that extends along the reflector and has a shape that is dependent on the shape of the reflector.

    摘要: A method and apparatus are disclosed for forming an image from millimetre waves. A field of view scanned using two geometrically orthogonal, intersecting copolarized fan beams (110, 120) to receive millimetre wave radiation. The received millimetre wave radiation from said fan beams are then cross-correlated (250, 650). Also, a method and antenna (400, 610) for receiving millimetre wave radiation are disclosed. The antenna includes first and second fan beam antennas (410, 420) for receiving millimetre wave radiation and a filter (430, 440) for rotating polarization of incident millimetre wave radiation through 90 degrees received by the second fan beam antenna (410). The respective first and second beams (110, 120) intersect and are co-polarized and geometrically orthogonal to each other. Still further, a millimetre wave imaging system (600) and method are also disclosed, which utilise an antenna (610) for receiving millimetre wave radiation, process the received millimetre wave radiation from the antenna (610), and build up the image (682) using a filtered, cross-correlated signal.
