Abstract: The present disclosure relates to dielectric duplexers. One example dielectric duplexer includes a dielectric body, where an input/output structure, a tap, a first resonance structure, and a second resonance structure are provided on surfaces of the dielectric body. The tap and the input/output structure are provided on different surfaces of the dielectric body. The tap and the input/output structure are located between the first resonance structure and the second resonance structure. A first resonator consists of the first resonance structure and the dielectric body around the first resonance structure, and a second resonator consists of the second resonance structure and the dielectric body around the second resonance structure. A conducting layer covers a surface of the input/output structure, the tap, the first resonance structure, and the second resonance structure, and the conducting layer covers the surface of the dielectric body except a region around the input/output structure.
