    摘要: A technique for fabricating a patterned resistor on a substrate produces a patterned resistor (101, 801, 1001, 1324, 1374) including two conductive end terminations (110, 810, 1010) on the substrate, a pattern of first resistive material (120, 815, 1015) having a first width (125) and a first sheet resistance, and a pattern of second resistive material (205, 820, 1020) having a second width (210) and a second sheet resistance that at least partially overlies the pattern of first resistive material. One of the first and second sheet resistances is a low sheet resistance and the other of the first and second resistances is a high sheet resistance. A ratio of the high sheet resistance to the low sheet resistance is at least ten to one. The pattern having the higher sheet resistance is substantially wider than the pattern having the low sheet resistance. The patterned resistor can be precision trimmed 1225.

    摘要: An integrated patch antenna and electronics assembly (300) comprises an antenna dielectric layer (305), a ground plane layer (310) disposed on a first side of the antenna dielectric layer, a printed circuit dielectric layer (315) disposed on the ground plane layer opposite the antenna dielectric layer, a patterned conductive metal foil layer (320) on a component surface (323) of the assembly (300), and a conductive metal foil antenna patch (325) disposed on a second side of the antenna dielectric layer that is in a patch side (391) of the assembly. In some embodiments, a plated through hole (330) couples the antenna patch to the patterned conductive metal foil layer. In some embodiments, there are one or more printed circuit dielectric layers (316, 341, 346, 351) disposed over the antenna patch on the antenna patch side of the assembly. In some embodiments, pairs of printed circuit dielectric layers ([315, 316], [340, 341], [345, 346], [350, 351]) are formed simultaneously on each side of the assembly.
