摘要：PROBLEM TO BE SOLVED: To provide a circularly polarized wave antenna to be used for communication between a static satellite and a mobile station, which is suitable for miniaturization, and resistant to vibration. SOLUTION: A dielectric substrate 3 constituted of dielectric materials such as ceramic is formed into a quadratic prism shape, and a plane view quadrangular through-hole 5 is formed at the center. Radiating conductors 4 whose shapes are the same are formed on the four side faces of the dielectric substrate 3 by a printing method or the like, and the respective radiating connectors 4 are inclined at about 45 deg.. A circular polarization antenna 1 is constituted by fixing the dielectric substrate 3 on a printed board 2, and soldering the lower edges of the respective radiating conductors 4 to the corresponding parts of the printed board 2, and in-phase power supply to the four radiating conductors 4 is operated.
