An antenna connector comprises a first housing for housing an end of a coaxial cable, first and second contact to be connected to a core wire and a shield wire, respectively, of the coaxial cable housed in the first housing, a second housing for housing the first housing, and a pair of conductive feeding metal plates. The feeding metal plates are arranged on and secured to a conductive antenna pattern formed on an insulative substrate and each of them has a first holder for receiving and holding the second housing and a second holder for receiving and holding the first and second contacts. When the first housing is housed in the second housing, the first and second contacts are engaged with and held by the second holder to plugably connect the coaxial cable to the antenna without disturbing an impedance matching and with a sufficient mechanical strength.
