Document Type and Number:
WIPO Patent Application WO/2021/079603
Kind Code:
A1
Abstract:
An antenna device (120) is formed such that 12 radiating elements each radiate circularly polarized waves, the elements being arrayed in a grid of three rows and four columns. The 12 radiating elements comprise four types of radiating elements (121a-121d), in sets of three apiece, that have positional relationships of rotational symmetry to one another. When n is any integer 1 to 3, m is any integer 1 to 4, and (ｎ×ｍ) is a grid location of an n-th row and an m-th column, then: the first type of radiating elements (121a) are arranged at (1×1), (2×3), and (3×1); the second type of radiating elements (121b) are arranged at (1×2), (2×4), and (3×2); the third type of radiating elements (121c) are arranged at (1×3), (2×1), and (3×3); and the fourth type of radiating elements (121d) are arranged at (1×4), (2×2), and (3×4).
