Abstract: An antenna structure includes a dielectric lens, an antenna substrate on the dielectric lens, and antenna electrodes on the antenna substrate. Each of the antenna electrodes may include a wire electrode and an empty plane having a triangular shape defined by the wire electrode. The antenna structure can reduce periodic reflection of a high frequency signal, suppress a periodic gain reduction phenomenon, and provide flat gain characteristics in a wide frequency band.
