A Study of Meander Line Polarizer Based on Equivalent Circuits

This paper proposes a method of equivalent circuit design. A technique was examined for formulating an equivalent circuit model of a meander line polarizer, and calculating electrical characteristics without using numerical analysis. Also, precision of the technique was improved by multiplying each derived lumped constant by a correction equation found from the difference with numerical analysis. In addition, a 4-layer meander line polarizer was designed using this technique, and the results were confirmed to match with numerical analysis within a range of error of 4%.
