Title:
RADIO WAVE SENSOR APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/034152
Kind Code:
A1
Abstract:
This radio wave sensor apparatus comprises an oscillator which generates a high-frequency signal, a transmission antenna (10), a reception antenna (11), a mixer, and a signal processing device. The transmission antenna (10) has a transmission antenna part (21) and a transmitting horn part (22A), and the reception antenna (11) has a reception antenna part (23) and a receiving horn part (24A). The transmission antenna part (21) and the reception antenna part (23) are arranged on the same flat surface so as to be spaced apart from each other. An inner wall of the transmitting horn part (22A) and an inner wall of the receiving horn part (24A) bear a wall portion (27) for separating the transmission antenna (10) and the reception antenna (11). The wall portion (27) has a wall surface area that spans from the opening end side of the transmitting horn part (22A) and the receiving horn part (24A) toward the transmission antenna part (21) and the reception antenna part (23), and that is perpendicular to the flat surface. The transmitting horn part (22A) and the receiving horn part (24A) are arranged adjacent to each other with the wall portion (27) therebetween.
