摘要

A planar antenna according to the invention is provided with: a planate radiation conductor 11; a common ground conductor 32; a first strip conductor 21 located between the planate radiation conductor 11 and the common ground conductor 32 and extending, in a first right-handed Cartesian coordinate system having first, second and third axes, in a direction parallel to the first axis; a second strip conductor 22 located between the planate radiation conductor and the common ground conductor and extending in a direction orthogonal to the direction in which the first strip conductor extends; and at least one pair of parasitic conductors 12 to 15 each forming an angle of 45 ± 3 degrees or −45 ± 3 degrees with respect to the first axis and having a side opposed to the planate radiation conductor.
