The purpose of this manuscript is to present a compact design strategy for bandpass filters using Meander Line Resonators (MLR) in combination with Stub Loaded Resonators (SLR). The proposed resonator has been designed and analyzed using even-odd mode analysis. Open-ended stubs are loaded at an appropriate position in the dual-mode resonator to achieve tri, quad, and quintuple passbands. To reduce the circuit size and create transmission zeros at our desired frequencies, a symmetrical meandered shape resonator is loaded with open-ended identical stubs which are bent towards each other. A design strategy is presented step by step and the approach is validated using simulation and experiments.
