Title:
SIGNAL LINE MODULE AND COMMUNICATION TERMINAL DEVICE
Document Type and Number:
Japanese Patent JP2015167377
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To configure a signal line module for reducing deterioration in an antenna characteristic of a radiation element while reducing loss of transmission power.SOLUTION: A first connection unit 11 connected to a feeder circuit, a second connection unit 12 connected to a radiation element, a first high-frequency line unit 21, a second high-frequency line unit 22, and a matching circuit unit 30 configuring all or part of a first matching circuit are provided integrally on a laminate composed of a plurality of stacked base material layers. The first connection unit 11, first high-frequency line unit 21, and matching circuit unit 30 are formed in a ground zone GZ overlapping with a ground conductor in a plan view from a stacking direction of the laminate; and the second high-frequency line unit 22 and second connection unit 12 are formed in a non-ground zone NGZ. The second high-frequency line unit 22 and second connection unit 12 as well as the radiation element act as a radiation unit.
