AI Technical Summary
Technical Problem
Existing vehicle antennas cannot fully achieve the desired antenna gain in the desired direction.
Method used
An antenna for vehicles is designed, which adopts a structure of a conductor plate, a radiating plate, a power supply unit and a connecting conductor. The antenna gain characteristics are optimized by arranging first and second elements on both sides of the radiating plate and setting the radiating plate at an angle within ±15° relative to a vertical plane perpendicular to the horizontal plane.
Benefits of technology
The antenna gain was improved in the desired direction, and a proper gain balance was achieved, particularly in the vehicle's direction of travel and width.

Abstract
The present application provides a vehicle antenna, a window glass with the vehicle antenna, and an antenna system. The vehicle antenna includes a conductor plate, a radiating plate disposed opposite the conductor plate, a power supply portion located on a side of the conductor plate with respect to the radiating plate, a connecting conductor connecting the power supply portion and the radiating plate, and first and second elements disposed on both sides of the vehicle in a vehicle width direction, respectively, with respect to the radiating plate. The radiating plate is disposed at an inclination of ±15° or less with respect to a vertical plane perpendicular to a horizontal plane.
