Abstract

See full text

A planar antenna includes: first and second conductors each of which forms a microstrip line in combination with a ground electrode, and which are arranged in parallel with each other on a substrate; a plurality of first resonators disposed between the first conductor and the second conductor which electromagnetically couple the first conductor at one longitudinal end of each of the first resonators to generate electric fields which are in phase with each other; and at least one second resonator disposed between the first conductor and the second conductor which electromagnetically couples the second conductor at one longitudinal end of the at least one second resonator to generate an electric field which is in phase with the electric fields generated by the plurality of first resonators, wherein the at least one second resonator is arranged alternately with the plurality of first resonators.
