Abstract: A method of manufacturing a sticker type antenna, in which a copper foil of 0.017 mm by thickness is stuck to a layer of releasable film in advance, in order that the copper foil can bear the pulling force in a brush electroplating process to thereby substitute the conventional beryllium copper of a larger thickness. The copper foil after brush electroplating undergoes punching and cutting for forming a pattern and is stuck to a semi-finished product of Mylar, hence the copper foil is stuck onto the back side of the Mylar layer; then the Mylar layer with the copper foil is separated from the releasable film, then the back side of the Mylar layer is applied with adhesive and again is stuck to the releasable film; after punching and cutting the Mylar layer for patterning and edging, a sticker type antenna is made.

Abstract: A RF microwave connector for telecommunication has a central terminal with a guiding groove and a fixing groove. The diameter of the cross section of the guiding groove is larger than the diameter of an inner wire of a coaxial cable and the diameter of the cross section of the upper end of the fixing groove is smaller than the diameter of the inner wire. The inner wire is thrust in the fixing groove by the walls of the fixing groove to cause the combination of the central terminal and the inner wire to be more stable and the connector to have better signal transmission quality by thrusting the inner wire into the fixing groove.
