A Theorem for Multi-Frequency DC-Feed Network Design

In this letter, a novel and rigorous analytical design approach formulated as a theorem for the exact design of arbitrary multi-frequency DC-feed network is presented. While the conventional method necessitates optimization to arrive at a near exact solution, the proposed theorem discards the need of optimization. Moreover, by blending the theorem with the power of today's RF/microwave CAD tools, a CAD assisted design methodology is proposed that is able to provide with exact design parameters very quickly. To demonstrate the effectiveness of the proposed theorem, several design cases have been worked out and compared with the existing design.
