Title:
LEAKY WAVE ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/039004
Kind Code:
A1
Abstract:
According to the present invention, a thin polarization sharing leaky wave antenna using a CRLH transmission line is realized which can achieve a high tilt angle for vertical in-plane directivity while suppressing cross polarization and side lobe at a target operating frequency. Specifically, the present invention provides a leaky wave antenna (A1) provided with: a dielectric substrate 2; a ground plane 9 formed on a lower surface of the dielectric substrate 2; ground parts 5, 6 formed on an upper surface of the dielectric substrate 2; a CRLH line disposed adjacent to the ground portions 5, 6, formed on the upper surface of the dielectric substrate 2, and using a coplanar line with ground, wherein a serial capacitor (CL)3 and a parallel inductor (LL)4 constituting the CRLH are formed on the upper surface of the dielectric substrate 2.
