1. A resonance circuit, comprising:
a connection port, wherein the connection port comprises a first port and a second port; and
a resonance unit, wherein the resonance unit comprises at least two inductor elements and at least two capacitor elements, and the at least two inductor elements are connected to the at least two capacitor elements,
wherein the first port and the second port are respectively connected to the at least two inductor elements, so as to form at least two branches connected in parallel, and each of the first port and the second port is not connected to any capacitor element,
wherein the at least two inductor elements and the at least two capacitor elements are in sequence connected end to end to form a closed ring circuit, wherein the first port and the second port are connected to different positions of the ring circuit to form the two branches connected in parallel.
