Title:
HIGH-FREQUENCY TRANSMISSION LINE, RADAR APPARATUS PROVIDED WITH HIGH-FREQUENCY TRANSMISSION LINE, AND RADIO DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/171658
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a high-frequency transmission line capable of suppressing transmission of unwanted frequency components in a signal and easily adjusting the frequency band to be suppressed. The high-frequency transmission line of the present invention is configured by laminating a plurality of conductor layers and an insulating layer, and is provided with: a signal via, which extends in a direction in which the conductor layers and the insulating layer are laminated and electrically connects the conductor layers together; an input line, which is arranged in one of the conductor layers and inputs an electrical signal to the signal via; a signal line, which is arranged in another one of the conductor layers and is connected to the input line through the signal via; a ground plane, which is arranged in any one of the conductor layers, is separated from the signal via, and is connected to a reference potential; a conductor arm part arranged within a separation region that separates the signal via and the ground plane from each other; and a conductor connection part arranged within the separation region and connecting the conductor arm part and the ground plane. The conductor arm part and the conductor connection part are configured to suppress an electrical signal of a predetermined frequency within an electrical signal.
