This article presents two microwave bandstop filters based on microstrip loop resonators with capacitors. The filters have steep band edges, are compact and easy to fabricate. They are applicable for protection against strong signals in nearby channels. Construction of filters, capabilities of band shift compensation, and tuning are discussed. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:993–997, 2014
