Title:
TRANSMISSION LINE, AND ELECTRONIC INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2021/006037
Kind Code:
A1
Abstract:
A first frequency of a high-frequency signal transmitted along a first signal line, and a second frequency of a high-frequency signal transmitted along a second signal line are higher than a third frequency of a high-frequency signal transmitted along a third signal line and a fourth frequency of a high-frequency signal transmitted along a fourth signal line. A first electrode pad connected to the first signal line, a second electrode pad connected to the second signal line, a third electrode pad connected to the third signal line, and a fourth electrode pad connected to the fourth signal line are formed on one main surface of an external connecting portion of the transmission line. Said one main surface includes a first region in which the first electrode pad and the second electrode pad are formed, and a second region in which the third electrode pad and the fourth electrode pad are formed. Each of the first electrode pad and the second electrode pad are surrounded by a ground electrode when seen in a plan view, and the third electrode pad and the fourth electrode pad include parts that are not surrounded by the ground electrode, at least partially, when seen in a plan view.
