The antenna is provided with: a conductor; an EBG structure that is disposed above the conductor and that contains plural square elements arranged in a matrix; and a radiation element disposed above the EBG structure. A distance L1 between the conductor and the EBG structure satisfies 0.01» 0 ‰¤ L1 ‰¤ 0.15» 0 , preferably satisfies 0.025» 0 ‰¤ L1 ‰¤ 0.085» 0 , and more preferably satisfies 0.035» 0 ‰¤ L1 ‰¤ 0.07» 0 , where an wavelength of a design center frequency of the radiation element is denoted by » 0 . |
