A Study of the Phase and Filter Properties of Arrays of Parallel Conductors between Ground Planes

摘要: A number of structures are analyzed which consist arrays parallel conductors between ground planes or above a single plane. These include interdigital line, meander form helix, "hairpin line," and reactively-loaded comb line. Equations derived for determining the phase function ? per section line in terms voltage coupling factors K1n obtained from static capacitances unit length conductors. image impedance finite three five cases considered. Data computing presented using small wires having conductor dimensions such that fringing capacitance beyond nearest neighbors can be neglected. Phase characteristics given various types results indicate certain have special merit use as filters, slow-wave structures. An interdigital-line filter ten was constructed found to excellent band-pass bandwidth is very good agreement with theory.
