PROBLEM TO BE SOLVED: To provide a planar antenna capable of reducing coupling between antennas of a same frequency without increasing areas of antennas.SOLUTION: The planar antenna includes: a dielectric substrate; a plurality of antenna elements, provided on one surface of the dielectric substrate, formed of an element pattern connected with a direct current to the ground, radiating an electromagnetic wave in the same frequency band by exciting the element pattern; and a parasitic antenna element, provided between antenna elements, which is a pattern connected with an alternating current to the element pattern by capacitive coupling. |
