摘要: A method to design TE01δ-mode dielectric-resonator (DR) filters with transmission zeros is proposed. The feeding probes, extended along ring DRs, are used excite the TE01δ mode and introduce zeros. By rotating angle of position, can be shifted lower or upper stopband. Thus, DR quasi-elliptic responses realized only iris coupling components. Based on this method, second- fourth-order different designed fabricated. Measured results confirm predicted performance.
