Claim 0:
1. An electronic device comprising:
a first multilayered printed circuit board (PCB) including a transceiver circuit;
a second multilayered PCB including antennas; and
a connector to connect the first multilayered PCB and the second multilayered PCB through a plurality of terminals,
wherein the first and second multilayered PCBs each includes signal transmission lines vertically connected for signal transmission between different layers thereof,
wherein the first and second multilayered PCBs each includes a plurality of ground patterns adjacent to one another to constitute a ground vertical-connection between different substrates, and
wherein window regions from which metal patterns are removed are formed between the adjacent ground patterns at the same position of different layers of the first and second multilayered PCBs, so as to improve a matching characteristic at the vertically connected signal transmission lines.
