Electromagnetic Parameters Measurement of Sheet Using Separate Microstrip Line

Abstract

A fixture for broadband electromagnetic parameters (εr and μr) measurement of sheet material is proposed. The novelty includes splitting the microstrip line in half to move calibration planes to sample fringes. By introducing a connecting strip and ground block and placing the sheet sample between them, a new microstrip line is constituted. Its effective electromagnetic parameters can be determined by the transmission/reflection method and actual electromagnetic parameters of the sheet can be calculated by the conformal mapping principle. The proposed fixture features two advantages over existing techniques, high calibration accuracy and more convenience for the measurement of the conductor-backed sheet.
