Small antenna apparatus for vehicle and manufacturing method therefor

The present invention relates to a small antenna device for a vehicle and a method for manufacturing the same. The device including integrated and simple components can be suitably installed in various circumstances, and the device and the method can reduce manufacturing costs. The small antenna device for a vehicle comprises: an antenna coil which is arranged in a helical antenna structure at certain pitch intervals; a connector which is arranged on one end of the antenna coil; a cylindrical member which is arranged on the other end of the antenna coil and includes a conductive pattern that is electrically connected to the antenna; a first fixing member to cover a portion of the connector and one end of the antenna coil so that the antenna coil can be fixed to the connector; a second fixing member which is included in a pitch space part within a certain pitch interval with a hollow part of the antenna coil; a third fixing member to cover the other end of the antenna coil; and a cover member to cover the antenna coil, a portion of the connector; the cylindrical member, the first fixing member, the second fixing member, and the third fixing member, wherein the first fixing member, the second fixing member, and the third fixing member are formed to be integrated.
