Abstract: A microwave filter is disclosed, which filters only a signal of a desired band in a radio communication system. The microwave filter includes a plurality of feed lines and resonators on an upper portion of a substrate, and a ground surface below the substrate. Each of the resonators includes coupled meander lines, the meander lines having three or more sections. The resonators are arranged in such a manner that the adjacent resonators are symmetrical to each other. The feed lines are formed at one side of the resonators at both edges, and are coupled spaced apart from the resonators in parallel to the resonators. Thus, the microwave filter can be fabricated at a small size because the meander-lined resonators have a small size. The microwave filter also has excellent transmission characteristics such as pseudo-elliptic characteristics.
