Description of the Invention: [Technical Field] The present invention relates to an antenna, and more particularly to a cross-polarized antenna in which two antennas integrally formed in an integrated manner are arranged to cross each other. [Prior Art] The radio frequency signal output by the radio transmitter is transmitted to the antenna by the feeder, and then radiated to the outside in the form of electromagnetic waves. When the electromagnetic wave is transmitted to the receiving point, the electromagnetic wave is received by the antenna, and the RF signal is transmitted to the radio receiver via the feeder. Generally, the antenna radiates electromagnetic waves to the surroundings, and the electromagnetic waves are composed of an electric field and a magnetic field. The direction of the electric field is the polarization direction of the antenna. Therefore, the electromagnetic waves that the antennas of different polarization characteristics can receive and radiate also differ depending on the polarization direction. If the antenna is polarized differently from the electromagnetic wave it receives, it will cause polarization loss, making the received signal smaller. © For example, when a polarized antenna in the vertical direction is used to receive electromagnetic waves in the horizontal polarization direction, the received signal will become very small, that is, polarization loss occurs, and the polarization loss is maximum at this time. Therefore, in order to reduce the polarization loss, the antenna should be able to effectively receive signals of different polarization directions. In addition, the structure of the general antenna is complicated, and the manufacturing and assembly processes are relatively difficult, so that the manufacturing and assembly process of the antenna should be effectively simplified and the relative manufacturing cost should be reduced. 5 200926515 [Delete. Contents] In order to solve the polarization loss caused by the polarization direction of the above-mentioned antenna and the electromagnetic wave received by it, and the complicated structure of the antenna makes the manufacturing and assembly process difficult, the present invention proposes a cross-polarization The antenna, which effectively receives electromagnetic waves of various polarization directions, is more convenient to manufacture and assemble by the integrally formed design, thereby reducing manufacturing costs.
