| Summary: | The utility model relates to the field of radio frequency devices, and provides a filter, which comprises a filter shell and a plurality of resonance rods arranged in the filter shell, and is characterized in that each resonance rod is provided with a connecting end connected with the filter shell and a free end opposite to the connecting end; at least one resonance rod is provided with a coupling part between the connecting end and the free end, and the coupling part extends towards the adjacent resonance rod and is used for being capacitively coupled with the adjacent resonance rod; an adjusting space is formed between the free ends of every two adjacent resonance rods. According to the filter, the coupling part extending towards the adjacent resonance rod is arranged between the connecting end and the free end of at least one resonance rod, so that the two adjacent resonance rods can be capacitively coupled through the coupling part, and the coupling strength and the coupling effect between the two adjacen |
