The composite elements each include a rectangular microstrip line element, an input microstrip line and an output microstrip line. The microstrip line element has one longer side, the other longer side, one end and the other end, and the input microstrip line is connected at the one end to the one longer side while the output microstrip line is connected at the other end to the other longer side. The composite elements are cascaded to constitute a low-pass filter.
