ARCHITECTURE OF AN EXTENDED TWO-DIMENSIONAL ARRANGEMENT FOR THE SYSTEM OF PHASED ANTENNA ARRAYS WITH ACTIVE SCAN

摘要

Systems and methods according to one or more examples are provided for a scalable planar phased array antenna subarray tile assembly. A scalable phased array antenna subarray tile assembly is implemented as a printed wiring board (PWB) with antenna elements coupled to the PWB. In one example, a PWB includes integrated circuit die attached directly to a first surface of the PWB and couple to antenna elements coupled on a second surface of the PWB. First conductive vias extend through a first subset of PWB layers and couple to the integrated circuit die. Second conductive vias, larger than the first, extend through a second subset of PWB layers and couple to the antenna elements. A conductive trace couples the first and second conductive vias on a PWB layer. The second conductive vias are offset from the first to provide a thermal mechanical stress relief to the integrated circuit die.
