Abstract
According to an aspect of the invention, there is provided an antenna apparatus comprising: a substrate comprising an end portion; antenna elements connected to the end portion through a connecting portion; and a conductive line path provided between adjacent antenna elements, both ends of the conductive line path connected to the end portion. A distance between both ends of the conductive line path is shorter than a quarter wavelength of an operating frequency of the antenna elements. A path difference between a first path length from an connecting portion of one of the antenna elements to an connecting portion of the other of the antenna elements through both ends of the conductive line path and a second path length from the connecting portion of one of the antenna elements to the connecting portion of the other of the antenna elements through the conductive line path is a half wavelength of the operating frequency.
