Title:
ANTENNA CABLE NOISE SUPPRESSION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/090031
Kind Code:
A1
Abstract:
An antenna cable noise suppression structure (1) comprises: a plurality of antenna cables (10); and a noise suppressing member (20) which is electrically conductive and which is electrically connected to outer conductors (13) of each of at least two antenna cables (10). Furthermore, the noise suppressing member (20) is electrically connected to the outer conductor (13) of each antenna cable (10) in a position in which a distance from an end portion (10a) of each antenna cable (10) is at most equal to one quarter of a wavelength (λ) calculated on the basis of a frequency (f) of a signal transmitted by each antenna cable (10). In addition, the noise suppressing member (20) and the outer conductor (13) that is electrically connected to the noise suppressing member (20) are grounded to a grounded portion (70).
