摘要： The present invention is directed to an interface for connecting a waveguide manifold of a transition to a stripline manifold of the transition. The interface may include a plurality of metamaterial layers, each including a metamaterial(s). The interface may further include a ground plane layer which may be connected to both the plurality of metamaterial layers and to the stripline manifold. Further, the interface may include a plurality of ground vias which may form channels through each of the layers of the interface and through the stripline manifold for providing a ground structure for the interface. The interface is further configured for forming a resonant structure which provides a low-loss, broadband conversion between a stripline mode and a waveguide mode for electromagnetic energy traversing through the interface between the waveguide manifold and the stripline manifold.

摘要： A phased array antenna is provided having a plurality of phase shifter devices for phase shifting and beam steering a radiated beam of the phased array antenna. The plurality of phase shifter devices are interconnected with an interconnect structure comprising a plurality of linear array substrate slats. Each linear array substrate slat includes a plurality of radiating elements formed using first and second metal layers of the substrate slat, a plurality of phase shifter devices and a common RF feed conductor for the plurality of radiating elements. The common RF feed conductor is formed on a third metal layer of the substrate slat that is disposed between the first and second metal layers. The common RF feed conductor is configured to include a single location for electrical connections to receive RF signals for the plurality of radiating elements. The phased array antenna also includes bias/control conductors applied to selected areas of the third metal layer, a fourth metal layer applied over the second metal layer and a shielding metal layer applied on the fourth metal layer. The bias/control conductors are configured to include a single location for electrical connections to receive bias voltages and control signals. The fourth metal layer includes circuit connections from the bias/control circuitry to the plurality of phase shifter devices. Each phase shifter device is attached to a radiating element via a mounting location on the shielding metal layer. Accordingly, a phased array antenna interconnect structure is provided that reduces the number of electrical connections required to provide RF signals and bias/control signals to multiple radiating elements and phase shifters, respectively, of the phased array antenna and provides a cost effective phased array antenna architecture that has a single locus of electrical connection for RF and bias control signals embedded in a multi-layer linear array or slat substrate of the phased array antenna.

摘要： A power substrate module having a multilayer circuit board or laminated circuit board for use in a motor controller is described. The power substrate module includes pair of switching devices coupled across a direct current bus for converting direct current power from the bus to controlled alternating current power in response to control signals. The circuit board includes a first conductive layer, a second conductive layer and an insulative layer separating the conductive layers. The first and second conductive layers each include a conductive bus region, one of which is coupled to the first switching device and forms a high side of the direct current bus, and the other of which is coupled to the second switching device and forms the low side of the direct current bus.

摘要： A phased array antenna is made up of linear arrays. Each of the linear arrays has a printed circuit board spine. Split waveguides are formed from two symmetrical portions conductively joined to ground on opposite sides of the printed circuit board spine. Planar transmission line-to-waveguide transitions are mounted on the printed circuit board spine within the split waveguides. Phase shifter/TTD devices are mounted on the circuit board spine within the split waveguides for steering the phased array antenna beam. Bias and control circuitry is etched on the circuit board spine for biasing and controlling the phase shifter/TTD devices. The phased array antenna may be made up of the linear arrays combined into a two-dimensional array and fed with a waveguide feed or a printed feed manifold attached to the printed wiring board spine.
