PURPOSE: A circularly polarized antenna in a wireless communication system and a method for manufacturing the same are provided to generate a circularly polarized wave with a high gain. CONSTITUTION: An electricity supplying antenna(330) is located on a fixed point of a ground substrate(350). A plurality of conductive structures(320) is arranged on an upper cover in the same direction. A unit antenna includes the conductive structures. The upper cover is separate from the ground substrate. If the electricity supplying antenna radiates a linearly polarized wave, the conductive structures and the unit antenna radiate circularly polarized waves and radiate dual circularly polarized waves based on the number of electricity supplying antennas. |
