The present invention relates to a method of manufacturing a horn array antenna, comprising the steps of injection molding the body of the horn array antenna using a plastic resin, pre-processing the horn array antenna body using a chemical to improve the adhesion of the conductive material And coating the conductive metal thin film on the horn array antenna body by a sputtering method. As a result, even if the metal thin film is thinly coated, sufficient resistance value can be obtained, so that the antenna can be reduced in size and weight while maintaining or improving the performance of the antenna, and the cost can be reduced. |
