A METHOD AND SYSTEM FOR MULTI-FREQUENCY DC-FEED NETWORK DESIGN.

摘要

The present invention discloses a method for determining the electrical length 1..k of a horizontal transmission line (TL) by using the concept that cotangent of electrical length of any horizontal TL section (coti) is equal to the net imaginary-part of the admittance of the preceding stages while looking towards the left, divided by the characteristic admittance of that horizontal TL section. The input RF port, n0, remains open circuited during this evaluation.�
