PROBLEM TO BE SOLVED: To shorten the working time of impedance matching in place of impedance matching using offset power feeding. SOLUTION: This patch antenna with a patch element 101 arranged over a ground board 102 with a prescribed interval includes a power feeding conductor 105 which is a conductor, one end of which is connected to a coaxial connector 104 attached to a hole of the ground board and feeds the power to the patch element, and a current path changing metal fitting 106 which is a conductor capable of changing the current path by replacing a conductor in a different shape between the other end of the power feeding conductor and the patch element and perform impedance matching of the power feeding to the patch element.
