PRINTED CIRCUIT BOARD FOR DECREASING WIRELESS WIDE AREA NETWORK NOISE

摘要

PURPOSE: A printed circuit board for decreasing wireless wide area network noise is provided to reduce the wireless broad band network noise by corresponding the isolation pattern and the second signal line group. CONSTITUTION: The first signal line group(12) and isolation pattern(26) are formed on the first layer(10). The second layer(20) is formed between the first layer and insulating layer(30). The second signal line group(22) is formed on the second layer. The isolation pattern corresponds to the second signal line groups. The isolation pattern and the second signal line group are electrically connected through the via hole.
