Air bridge double-layer copper inductor structure and filter

The utility model discloses an air bridge double-layer copper inductor structure which comprises a first annular copper layer and a second annular copper layer, the first annular copper layer is provided with a first notch and a first pin, the second annular copper layer is provided with a second notch and a second pin, and the second annular copper layer is arranged above the first annular copper layer. A first interlayer connecting part and a second interlayer connecting part are clamped between the first interlayer connecting part and the second interlayer connecting part; the second annular copper layer is provided with a plurality of first supporting feet which are arranged at intervals, and the first supporting feet extend outwards in the radial direction from the outer periphery of the second annular copper layer and are supported on the substrate through one-time bending. The Q value of the inductor is improved, and when the inductor is applied to a filter, the insertion loss characteristic of the fil
