Abstract：

Due　to　distributed　capacitance,　a　planar　printed　coil　has　self-resonance,　which　will　significantly　affect　self-inductance　and　mutual　inductance.　In　this　paper,　the　impact　of　self-resonance　on　self-inductance　and　mutual　inductance　of　two　coils　is　analyzed　by　the　equivalent　circuit,　and　the　calculations　of　apparent　self-inductance　and　apparent　mutual　inductance　are　derived.　The　analysis　results　can　well　explain　the　frequency　characteristics　of　the　planar　printed　coils＇　self-inductance　and　mutual　inductance　obtained　by　full-wave　simulation.　Finally,　the　correctness　of　the　analysis　results　derived　from　the　equivalent　circuit　has　been　verified　by　the　numerical　example.　©　2021　URSI.
