Pattern antenna

Abstract

A pattern antenna, with desired antenna characteristics, that is formed in a small area is provided. The pattern antenna includes a substrate, a ground portion formed on a first surface of the substrate, an antenna element portion, a short-circuiting portion, and a connecting portion. The antenna element portion is a conductor pattern including a conductor pattern in which a plurality of bent portions are formed. The conductor pattern is formed on the first surface of the substrate and, and is electrically connected to the grand portion. The short-circuiting portion includes a conductor pattern formed in a second surface, which is a different surface from the first surface. The conductor pattern is formed so as to at least partially overlap with the conductor pattern of the antenna element portion as viewed in planar view. The connecting portion is configured to electrically connect the conductor pattern of the antenna element portion to the conductor pattern of the short-circuiting portion.
