Title:
SIGNAL LINE MODULE AND COMMUNICATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2014/050238
Kind Code:
A1
Abstract:
The present invention constitutes a signal line module and a communication terminal in which the loss of transmission power is reduced and the deterioration of the antenna characteristics of a radiation element is minimized. A first connection part (11), which connects to a power feeding circuit, a second connection part (12), which connects to a radiation element, a first high-frequency line part (21), a second high-frequency line part (22), and a matching circuit part (30), which constitutes some or all of a first matching circuit, are integrally disposed on a laminate obtained by laminating a plurality of substrate layers. The first connection part, the first high-frequency line part (21) and the matching circuit (30) are formed in a ground region (GZ) that overlaps with a ground conductor in a plan view from the lamination direction of the laminate. The second high-frequency line part (22) and the second connection part (12) are formed in a non-ground region (NGZ). The second high-frequency line part (22) and the second connection part (12) operate in conjunction with the radiation element as radiation parts.
