Abstract
A microstripline filter that includes principal-surface lines, a ground electrode, and input/output electrodes. A first principal-surface line is capacitively coupled to a second principal-surface line. The second principal-surface line is inductively coupled to a third principal-surface line. The third principal-surface line is capacitively coupled to a fourth principal-surface line. The first through fourth principal-surface lines include open-end-side electrodes, short-circuit-end-side electrodes, and end-opened electrodes. A first pair of the end-opened electrodes are adjacent to each other, whereas a first pair of the short-circuit-end-side electrodes are separate from each other. A second pair of end-opened electrodes are adjacent to each other, whereas a second pair of short-circuit-end-side electrodes are separate from each other.
