ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/170074
Kind Code:
A1
Abstract:
An electronic device (10A) comprises a transmission line (20A) and a circuit board (30A). The transmission line (20A) includes a base material (21), a signal conductor (231), a first external connection conductor (251), a second external connection conductor (252), and ground conductors (241, 242), and collectively forms a stripline. The circuit board (30A) is provided with a first mounting land conductor (341), a second mounting land conductor (342), and a radiation suppression conductor (33A). The first mounting land conductor (341) and second mounting land conductor (342) are formed in a recess (300) in the surface of the circuit board (30A) and are respectively connected to the first external connection conductor (251) and second external connection conductor (252). Radiation suppression conductors (343) are formed on the side surfaces of the recess (300) where the transmission line (20A) is disposed and abut or are proximate to a first side and a second side.
