A multiple-band antenna having first and second operating frequency bands is provided. The vibrating beam has a meandering-shape substantially formed into the plurality of continuous turned-down shapes. The connections control the movement of the piston inside the cylinder so that the piston can move between a first dead center position and a second dead center position thereby causing a stamp to affix a label to the package. The combined single-ended and differential signal interface does not increase the number of pins required for a single-ended only interface. A sidewall of one of the second pivot portion of the rotary member and the second connecting member defines a limiting structure.
