Design guidelines for air core coils in LTCC RF devices have been equivocal, because coils have the RF magnetic flux not only inside but also outside. In order to make a design rule for LTCC devices, the magnetic fields of coils and the influential traits from the adjoining components in the devices was analyzed. Consequently, the analysis results showed that the outside flux mainly exists within 200μm around the coil electrode and that the adjacent components make coil's impedance higher. The effects of the serial connection of air core coils with smaller number of turn on the self-resonance frequency were studied. The simulation results showed that the self-resonance frequency dose not shift higher.
