Abstract

A printed filter includes a first resonator, a second resonator, and a third resonator. The first resonator, the second resonator, and the third resonator each include an open-circuit segment and two short-circuit segments. Each short-circuit segment of the first resonator, the second resonator, and the third resonator are grounded. The two short-circuit segments of the respective first resonator and the second resonator are connected to form an L-shape. The open-circuit segment of the respective first resonator and the second resonator connects to its respective L-shape to form an arrow. The two short-circuit segments of the third resonator are connected to form a straight line. The open-circuit segment of the third resonator connects to the straight line of the third resonator to form a T-shape. One of the short-circuit segments of each of the first resonator and the second resonator is parallel to the straight line of the third resonator.
