Patch antenna and method for making the same

摘要

Disclosed is a patch antenna which has a driven patch which is fed with a high-frequency signal and radiates a high-frequency electromagnetic field from its one surface; a parasitic patch which receives the high-frequency electromagnetic field from the driven patch at its one surface and reradiates the high-frequency electromagnetic field from its other surface; and a radome which contains the driven patch and the parasitic patch inside of the radome to protect them and holds the parasitic patch; wherein the parasitic patch is held by the inner surface of the radome which contacts the other surface of the parasitic patch and a holder which protrudes from the inner surface of the radome and covers a part of the one surface of the parasitic patch.
