摘要： A parabolic aerial comprises a parabolic mirror (2), an exciter (3) for transmitting electromagnetic waves to the parabolic mirror, and a diffusion disc (1) for laterally removing interfering fraction of electromagnetic waves past the exciter. The parabolic mirror concentrates the electromagnetic waves. The diffusion disc is arranged in the center of parabolic mirror. The shape of diffusion disc is such that a beam of parallel radiation that impinges the diffusion disc along an axis from the exciter is diverted from the axis by a backscatter process at the diffusion disc. Independent claims are included for: (1) a fill level radar; and (2) fill level measurement.

摘要： A multi-band reflector antenna having a main reflector (50), a sub reflector (52), a first feed (60) and a second feed (58). The first feed, the sub reflector and the main reflector are positioned in a Gregorian optic configuration wherein an output of the first feed is directed to the sub reflector, from the sub reflector to the main reflector and from the main reflector into a first beam. The sub reflector may be shaped to distribute the output of the first feed reflecting off the sub reflector onto the main reflector whereby a central area of the main reflector has a lower illumination than a surrounding outer area of the main reflector and or is elongated vertically. The second feed projecting from a hole (62) in the sub reflector is oriented whereby an output of the second feed is directed to the main reflector and from the main reflector into a second beam.

摘要： A common aperture reflector antenna and feed are provided for use in common aperture sensor systems. The feed includes an array of individual elements. The array elements are configured to increase the overall efficiency of a reflector antenna by flattening the aperture illumination, and also by nullifying the illumination within the centrally-blocked-portion of the reflector antenna surface. More specifically, the array elements are carefully configured with respect to spacing and excitation, for example, such that the array illuminates only the non-blocked portion of the main reflector. In addition, the array pattern is optimized such that the non-blocked portion of the reflector antenna is quasi-uniformly illuminated.

摘要： A dual-reflector microwave antenna comprises the combination of a paraboloidal main reflector having an axis; a waveguide and dual-mode feed horn extending along the axis of the main reflector, a subreflector for reflecting radiation from the feed horn onto the main reflector in the transmitting mode, and a shield extending from the outer edge of the main reflector and generally parallel to the axis of the main reflector, the inside surface of the shield being lined with absorptive material for absorbing undesired radiation. The subreflector is shaped to produce an aperture power distribution that is substantially confined to the region of the main reflector outside the shadow of the subreflector. The support for the subreflector is preferably a hollow dielectric cone having a resonant thickness to cause energy passing through said cone to be in phase with energy reflected off of said cone so as to achieve phase cancellation.

摘要： The present invention relates to a metamaterial antenna, where the metamaterial antenna includes an enclosure, a feed, a first metamaterial that clings to an aperture edge of the feed, a second metamaterial that is separated by a preset distance from the first metamaterial and is set oppositely, and a third metamaterial that clings to an edge of the second metamaterial, where the enclosure, the feed, the first metamaterial, the second metamaterial, and the third metamaterial make up a closed cavity; and a central axis of the feed penetrates center points of the first metamaterial and the second metamaterial; and a reflection layer for reflecting an electromagnetic wave is set on surfaces of the first metamaterial and the second metamaterial, where the surfaces are located outside the cavity. The present invention uses distinctive electromagnetic properties of the metamaterial, and performs reflections of the electromagnetic wave for multiple times to improve aperture efficiency of the antenna and accomplish good far-field radiation field responses. In addition, the design of reflecting the electromagnetic wave for multiple times reduces thickness of the antenna significantly and makes an antenna system smaller.

摘要： The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. By applying a variable reactance (capacitive or inductive component) antenna aperture tuner within a simple, scalar antenna aperture tuning system, the maintenance of a constant antenna resonant frequency in the presence of environmental changes or head/hand effects is obtained. The variable reactance is used to adjust the resonant frequency of the antenna to stay at the desired target frequency in response to external variables that would otherwise shift the resonance away from the operating frequency of the device. Adjusting the resonant frequency of the antenna in response to externally induced changes maintains the radiating efficiency of the antenna and simultaneously avoids impedance mismatch between the antenna and the respective transmit/receive path in the radio, thereby minimizing transmission losses.
