Abstract
In an antenna including a dielectric window and a slot plate provided on one surface of the dielectric window, in a case where a reference position g is a center position in a width direction of each slot S and a center position in a length direction in the slot plate, the reference position g of each slot is located on a virtual circle centered on a center of gravity G, and line segments connecting the reference positions g of the slots S and virtual point Gto which the slots belong are located radially from a virtual point G, angles (βto β) between adjacent line segments are equal to each other, and angles (θto θ) formed by the length directions of the slots S at the reference positions g and the line segments to which the slots belong are equal to each other.
