| Summary: | 碩士 === 義守大學 === 電子工程學系 === 92 === Microstrip, with low cost and easier fabrication, was adopted as planar inductors in the microwave circuits. In this work, planar inductors were divided into two categories: spiral inductors and meander inductors. A spiral inductor is one-port type, whereas meander one is a two-port inductor.
The simulator IE3D was adopted to simulate the electrical properties of inductors. The effects of the line width, line pitch, and number of turns on the inductance and quality factor of the inductors were investigated. The simulated results were compared with those of the measured ones. The measured inductance approximates that of the simulated ones. There is a little deviation of quality factor between the measured and simulated results in low frequency range. The quality factor of measured inductors approximates that of the simulated one in high frequency range.
We focus on the establishment of an equivalent circuit model for meander inductors. Each parameter of the equivalent circuit model was calculated. Both the Serenade SV8.5 and IE3D simulators were employed to simulate the response of the meander inductors. The measured results were also compared with those of the simulated ones. The measured results were found to be in close agreement with those of the simulated results by IE3D or SV8.5. The proposed equivalent circuit model can predict the frequency response of the meander inductors.
