Document Type and Number:
WIPO Patent Application WO/2017/141600
Kind Code:
A1
Abstract:
An antenna device (100) is equipped with a plate-like dielectric substrate (1), an antenna element (2) provided on the dielectric substrate (1), and a stub element (3) provided on the dielectric substrate (1). The dielectric substrate (1) has a first edge extending along the lengthwise direction of the dielectric substrate (1), and a second edge extending along the lengthwise direction of the dielectric substrate (1) and facing the first edge. The antenna element (2) is provided along the lengthwise direction of the dielectric substrate (1). The antenna element (2) has a first end part having a power supply point (P1), and a second end part having an open end. The stub element (3) is provided along the lengthwise direction of the dielectric substrate (1) between the first edge of the dielectric substrate (1) and a section of the antenna element (2) that has a predetermined length and includes the first end part of the antenna element (2).
