Abstract
A patch antenna has: a driven patch fed with a high-frequency signal and radiates a high-frequency electromagnetic field from its one surface; a parasitic patch receives the high-frequency electromagnetic field from the driven patch at a first surface and reradiates the high-frequency electromagnetic field from a second surface; and a radome which protectively holds the driven patch and the parasitic patch inside of the radome; wherein the parasitic patch is held by the inner surface of the radome which contacts the second surface of the parasitic patch and by a holder which protrudes from the inner surface of the radome and covers a part of the first surface of the parasitic patch.
