Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/235593
Kind Code:
A1
Abstract:
In this antenna device, an isolation structure (10) that is provided between antenna elements (2, 3) is provided with: a conductor (11) that is provided on a surface of a dielectric substrate (1); and a plurality of via conductors (12) that electrically connect the conductor (11) and a grounding conductor (4) to each other by penetrating the dielectric substrate (1). When the specific dielectric constant of the dielectric substrate (1) is represented by εr, the wavelength of a signal transmitted from the antenna element (2) is represented by λ1 (mm), the height of the via conductors (12) is represented by h1 (mm), and the protruding length of the conductor (11) to the antenna element (2) is represented by d1 (mm), the value of (d1×2+h1)/(λ1/√εr) is within a range of 0.40-0.60.
