    摘要： An antenna array core comprising a plurality of microwave modules, a control layer, a mounting layer, and a signal distribution layer. The control layer is capable of distributing control signals to the plurality of microwave modules. The plurality of microwave modules are attached to an upper surface of the mounting layer and the mounting layer is made from a heat conductive material capable of cooling the plurality of microwave modules. The signal distribution layer is located below the mounting layer, wherein the signal distribution layer is capable of transmitting microwave signals to the plurality of microwave modules and wherein the arrangement of the plurality of microwave modules on the mounting layer, the control layer, and the wave distribution network form a layered architecture for the antenna core. The architecture is a balance between, size, thermal control, manufacturability, cost, and performance so as to be a unique solution.

    摘要： A dual beam electronically scanned phased array antenna architecture is provided. The architecture includes a plurality of antenna modules substantially orthogonally connected to a signal distribution board. Each module includes a radiator board substantially orthogonally connected to a first end of a support mandrel. Each radiator board includes a plurality of radio frequency (RF) radiating elements. Each module additionally includes pair of chip carriers mounted to opposing sides of the respective mandrel and interconnected to the respective radiator board. Furthermore, each module includes signal transfer board formed to fit around a second end of the mandrel such that the signal transfer board is compressed between the mandrel the signal distribution board. Each module further includes a pair of signal distribution bridges mounted to the opposing sides of the mandrel. Each signal distribution bridge interconnects the respective chip carriers with the signal transfer board and distributes digital, DC and/or RF signals received from the signal transfer board to a plurality of beam scanning circuits included in the respective chip carrier. The orthogonal relationship between the RF radiating elements and the beam scanning circuits allow the modules to be connected to the signal distribution board in close proximity to each other such that the RF radiating elements of adjacent modules have a spacing of one-half wavelength or less. Therefore, a high frequency, dual beam electronically scanned phased array antenna can be constructed that is capable of having scanning angles of 60° or greater. Therefore, a high frequency, dual beam electronically scanned phased array antenna can be constructed that is capable of having very wide scanning angles of without introducing grating lobes.

    摘要： A modularly expandable, phased array antenna having a rhomboidal shaped antenna aperture formed by a plurality of rhomboidal shaped subarrays. Each subarray has a rhomboidal shaped printed wiring board on which is formed a plurality of antenna elements, where the elements collectively form a rhomboidal shape in accordance with the printed wiring board. The rhomboidal shaped subarrays enable a modular aperture to be formed without producing any gaps between columns or rows of adjacently positioned subarrays. Thus, a uniform, consistent spacing is maintained between all the antenna elements on the subarrays. This improves antenna radiation and low observability performance for the antenna system, as well as reducing the overall size of the antenna aperture and its cost of construction.
