MEASURING SYSTEM WITH POSITIONING SYSTEM FOR BEAMFORMING MEASUREMENTS AND MEASURING METHOD
A measuring system comprising a measuring antenna, a link antenna and a positioning system is provided. The measuring antenna is configured to perform over the air measurements on a device under test. The link antenna is configured to perform communications with the device under test. The positioning system comprises a first rotational positioner, configured to rotate the device under test around a first axis. The positioning system further comprises a second rotational positioner, configured to rotate the measuring antenna around a second axis. The first rotational positioner is connected to the link antenna, and is thereby configured to rotate the link antenna around the device under test around the first axis.
Rotary antenna, scanner using such an antenna, and device for inspecting persons
The antenna comprises at least one waveguide of rectangular section and a cylinder having an opening along a helical line, the cylinder having a relative rotational movement in relation to the waveguide placed inside the cylinder, the waveguide being open facing the inner face of the cylinder which forms a microwave short-circuit to close the guide, wherein two cavities are produced on each side of the guide, parallel thereto, over its entire length, the openings of the cavities being substantially in the plane of the opening of the guide. The invention applies, for example, to the detection of hidden objects carried by persons, in particular dangerous objects.

Antenna system integrated with side-keys of an electronic device
This document describes methods and systems for an antenna system integrated with side-keys of an electronic device. The antenna system enables antenna integration in a metal frame using a metal support structure and fastener(s) to route antenna signals around side-key modules embedded in the frame without encountering or causing interference with the side-key modules. By using these techniques to integrate antennas on areas around the side-key modules, more antennas can be implemented on the electronic device, leading to improved capabilities supporting additional wireless standards and a better user experience in terms of improved communication quality.

Two-dimensional scanning cylindrical reflector
A parabolic cylindrical reflector antenna that comprises two or more antenna feeds each directed towards a parabolic cylindrical reflector, wherein the antenna feeds are positioned in one or more line-arrays parallel to a focal line of the parabolic cylindrical reflector, and the line-array is substantially centered opposing the reflector. The antenna comprises a controller configured to scan along a straight edge of the reflector by electronically adjusting a phase of each of the antenna feeds, thereby changing the incident angle of an energy beam relative to the reflector. The controller is configured to scan along a curved edge of the reflector by moving, using a mechanical positioning mechanism, the antenna feeds in a direction parallel to a directrix of the reflector while maintaining the positioning or by electronically selecting one of two or more parallel line-arrays.

Antenna horn with suspended dielectric tuning vane
A digital video broadcast satellite (DVB-S) television antenna horn assembly, reflector antenna, and a satellite communication system in which the antenna horn includes a suspended dielectric tuning vane that reduces the horn size, modifies the shape the reception pattern, and improves the antenna performance in a number of ways. The antenna horn and the dielectric tuning vane are configured to impart a combined differential phase shift protocol, such as CP polarization, on a circular polarity (CP) signal as the CP signal propagates through the horn from a reception aperture to an output aperture. The dielectric tuning vane may be built into the antenna horn, snap into the antenna horn, be built into a protective plastic lens cover that fits over horn opening, or designed to snap into the plastic lens cover. Various dielectric tuning vanes are suitable for single horn structures and multi-horn structures built into LNB amplifiers.
