Characterization of unbounded multiport microstrip passive circuits using an explicit network-based method of moments

摘要: This paper is concerned with a field-theoretical characterization of unbounded multiport microstrip passive circuits using an explicit network technique. The cornerstone this efficient modeling framework based on method moments (MoM) that makes use the representation generalized matrix parameters. To physically formulate equivalent for circuit, delta-gap voltage source backed by vertical electric wall conceptually introduced to terminate each port. In way, circuit be modeled externally connected at adequate location. image principle applied port remove and open environment can effectively simulated. With unified impressed model appropriate partition entire topology, MoM procedure developed extract parameters directly from formulations. All possible physical phenomena such as radiation leakage losses are incorporated in algorithm. Two distinctive examples presented demonstrate effectiveness proposed algorithm handling multilayered antenna circuits. Convergence analysis made filter example compared experimental results, showing very stable accurate. Theoretical results indicate implicit effects may influential electrical performance should considered design tool paper.
