ANTENNA, SUBSTRATE, AND COMMUNICATION DEVICE

WIPO Patent Application WO/2020/137137

A1

The purpose of the present invention is to provide a small dual polarization antenna using a split ring resonator, for example, and a substrate and a communication device for the antenna. An antenna (A1) is provided with antenna elements (a2) provided one by one on the respective sides of a substantially rectangular conductor plate (a1), for example. In the antenna (A1), each of the antenna elements (a2) is provided with a split ring conductor (a22) having a shape in which a ring is partially cut by a split part (a21) and a power feed line (a23), the power feed line (a23) is electrically connected to the split ring conductor (a22) and extends in a direction across a region formed inside the split ring conductor (a22), and the two antenna elements (a2) provided on arbitrary two sides facing each other of the conductor plate (a1) among the four antenna elements (a2) are each supplied with power through the power feed line (a23) included in each antenna element so as to have substantially the same direction of the electric field in a polarization direction.
