Microstrip Inductor Design and ImplementationAbstract
High frequency (HF) microstrip spiral inductor design using analytical formulation with network model and numerical simulation with planar electromagnetic simulator, Sonnet, are given for high power RF application. The simplified lumped element equivalent network model parameters for the spiral inductor are used to obtain the initial dimensions of the spiral inductor for simulation. The spiral inductor is then simulated with planar electromagnetic simulator, Sonnet, using the geometry constructed with the physical dimensions obtained from the network model for the desired inductance value. The parametric study of the spiral inductor is conducted to investigate the variation on its quality factor, self resonance frequency and inductance value. The spiral inductor is implemented on a ceramic substrate and measured. The measurement, simulation, and analytical results are found to be close.
