There is provided an electromagnetic coupler that communicates signals by using at least one of a longitudinal electrostatic field and a longitudinal induced electric field. The electromagnetic coupler has a ground conductor, a radiation conductor composed of a plurality of rectangular conductors connected in series, and a feeding point formed at one point in the connection of the plurality of rectangular conductors. The plurality of rectangular conductors are connected such that each pair of adjacent rectangular conductors form an angle other thanπradian, and a length from the feeding point to either end of the radiation conductor is an integral multiple ofλ/4 in electrical length with respect to a wavelengthλof a central frequency of a frequency band of interest of the electromagnetic coupler. |
