Title:
PATCH ANTENNA AND ON-VEHICLE ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/208056
Kind Code:
A1
Abstract:
Provided is a small, low-profile patch antenna that can stably receive signals of a plurality of frequency bands without incurring cost increases due to making the holding structure complex, or using materials that are expensive or materials for which processing and forming are difficult. A first radiating element 11 is provided on the upper surface of a dielectric 12 having two surfaces, and a second radiating element 13 on the lower surface of the dielectric 12. A base 14 made of resin for which the relative dielectric constant is lower than that of the dielectric 12 is placed between the second radiating element 13 and a ground conductor 15. The first radiating element 11 and the second radiating element 13 receive signals of different frequency bands.
