Title:
SIGNAL TRANSMISSION CABLE AND COMMUNICATION DEVICE MODULE
Document Type and Number:
WIPO Patent Application WO/2014/185231
Kind Code:
A1
Abstract:
Provided is a signal transmission cable equipped with a bandstop filter having a high Q factor. A signal-line conductor pattern (210) which includes a capacitor conductor (212) and an inductor conductor (213) is formed on a base material layer (101). The capacitor conductor (212) is formed in a planar shape, and the inductor conductor (213) is formed in a spiral shape. A signal-line conductor pattern (220) which includes a capacitor conductor (221) is formed on a base material layer (102). An inductor is constituted by the inductor conductor (213), and a capacitor is constituted by the capacitor conductors (212, 221) and the base material layer (101). The inductor and capacitor are connected in parallel by transmission conductors (211, 222, 223) formed on the base material layers (101, 102), and an interlayer connection conductor (401) formed on the base material layer (101).
