摘要： Embodiments of active array antennas are generally described herein. Other embodiments may be described and claimed. In some embodiments, a reflect array antenna includes an array of rectangular monolithic sub-array modules arranged in a non-uniform pattern to leave a plurality of rectangular gaps in the pattern. A DC feed pin located within each gap may provide DC bias current to the sub-array modules. The sub-array modules may be mounted on a heat sink in the non-uniform pattern. The heat sink may have holes aligned with the gaps to allow passage of the DC feed pins. In some embodiments, an array cooling assembly may be coupled to the back of the heat sink to cool the reflect array antenna with a coolant.

摘要： A modular solid-state MMW power source based on a topology of the lens array amplifier provides both the flexibility to scale output power and effective thermal management. The modular power source includes a single submodule that uses one or more power dividers and one or more solid-state amplification stages to divide and amplify an RF input signal into R amplified RF signals. The submodule is mounted (suitably in the X-Y plane) on the surface of a heat sink, suitably coupled to a cold backplane, to remove heat. R 1:N low loss power dividers route the amplified RF signals to R*N radiating elements. Each of the 1:N power dividers suitably reside in the X-Z plane and are stacked in the Y direction to provide a planar output of the R*N radiating elements in the Y-Z plane. Placement of the amplifier chips on the single submodule decouples the number of amplifier chips, hence output power, from the number of radiating elements. Placement of the amplifier chips away from the radiating face provides a short path with large thermal cross-section through the heat sink to the backplane to remove heat. The topology can produce high output power combined with a high antenna gain to produce large power-aperture products previously only achievable with a Gyrotron. As amplifier chips become more powerful, the topology can be adapted to use fewer chips.

摘要： There is disclosed an apparatus to test an antenna. A transmitter generates a test signal radiated by the antenna under test. A near field scanner includes a field sampling probe to capture electromagnetic energy radiated by an antenna under test. An x-y positioning system including x and y positioning motors moves the field sampling probe over a measurement surface disposed proximate to the antenna under test. A quasi-optical beam transport system couples at least a portion of the captured electromagnetic energy from the field sampling probe to a scanner output port. A receiver is coupled to the scanner output port.

摘要： A millimeter-wave window is constructed from a high conductivity metal plate. The metallic plate is made transparent over a range of frequencies by perforating it with a periodic array of slots. In one embodiment, the millimeter-wave window is used in a gyrotron as the output window. In such a case, one suitable periodic array of slots comprises an equilateral triangular array of slots for operation at 95 GHz. By proper choice of the hole spacing and diameter, the window can be made transparent at any desired frequency. In addition to being transparent, however, the window must also be vacuum tight, as the pressure inside a gyrotron is on the order of 10−9 torr. The present invention solves this problem by covering the surface of the window with a thin layer of a suitable dielectric material, such as fused quartz.

摘要： Embodiments of the invention are directed toward a novel printed antenna that provides a low-loss transition into waveguide. The antenna is integrated with a heat spreader and the interconnection between the antenna and the output device (such as a power amplifier) is a simple conductive connection, such as (but not limited to), a wirebond. Integrating the antenna with the heat spreader in accordance with the concepts, circuits, and techniques described herein drastically shortens the distance from the output device to the waveguide, thus reducing losses and increasing bandwidth. The transition and technique described herein may be easily scaled for both higher and lower frequencies. Embodiments of the present apparatus also eliminate the complexity of the prior art circuit boards and transitions and enable the use of a wider range of substrates while greatly simplifying assembly.
