Title:
LENS ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2015138999
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lens antenna device that is provided on a glass substrate having a curved surface shape and converges an electromagnetic wave in a millimeter wave zone from a target object into a predetermined position.SOLUTION: A lens antenna 100 is provided at a front glass 10 of a curved surface shape and converges a millimeter wave in a predetermined frequency zone incident from a front direction into a predetermined position (focal point) inside a vehicle. A sensor device 200 is provided at a predetermined position and two-dimensionally senses an intensity distribution of a millimeter wave in a predetermined wavelength to form an image of it.
