Patch antenna, which a linearly polarized shaft and produced in a circularly polarized wave, and a generation method thereof

摘要

A patch antenna, which a circularly polarized wave and a linearly polarized wave generated synchronously, has a first radiator, which a circularly polarized wave in relation to an antenna signal, a first substrate, which on a part of the rear face or the entire rear surface of the first radiator is provided, a second radiator, which is placed on a part of the rear face or the entire rear surface of the first substrate is provided, and a linearly polarized shaft in relation to the antenna signal, and a second substrate, which on a part of the rear face or the entire rear surface of the second radiator is provided.
