Abstract

In this work it is proposed and analyzed a new method of producing phase shifter elements from multiple threads coaxial microwire taking as example phase shifter at -45°. It shows the advantages of the proposed method compared to the well known method for the manufacture of above-mentioned elements from a single microwire. It is shown that the manufacture of phase shifter elements from several microwires improves electrical parameters n times, where n greater than 1: decreases the useful signal loss, decreases phase shift deviations from -45° conditioned by the finite value of insulation resistance of microwire, decreases resistance imperfection between microwire conductor and coaxial sheath.
