PROBLEM TO BE SOLVED: To suppress impact of a metal object existing in the vicinity of the antenna surface on the antenna characteristics by a simple configuration.SOLUTION: A slot antenna having a feed point, provided in the vicinity of a slot bored in a planar conductor, and transmitting/receiving radio waves of a wavelength λ, includes a planar first conductor in which a slot is bored, a planar second conductor, a dielectric held between the first and second conductors, and a plurality of connection means for connecting the first and second conductors electrically via the dielectric. The connection means are provided on both sides of the slot in parallel therewith, at a first interval of high frequency electrical length of λ/4 or less. |
