Characteristics of a Microstrip Two-Meander Ferrite Phase Shifter (Short Papers)

A derivation for the image impedance of a microstrip line with one basic meander is presented. This shows a bandpass characteristic. A new simple technique is followed in designing a two-meander line on a G500 ferrite substrate. Scattering measurements (S-band) made on a model show excellent agreement with theory. Measured nonreciprocal differential phase shift is shown.
