Resumen de Physical modeling, theoretical analysis, and experimental test of via holes in microwave planar circuits
Purpose – The purpose of this paper is to present the transmission and reflection characteristic of via holes in microwave planar circuits by the matrix‐penciled moment method (MP‐MOM) including physical modeling, theoretical analysis, and experimental test. Especially, the experimental test is given in detail including device under test design, fixture design, and de‐embedding method.
Design/methodology/approach – The MP‐MOM is used to analyze the transmission and reflection characteristic of via holes in a wide frequency band. An emulator is built on MATLAB program (M‐file) to explore the effects of various parameters of via holes.
Findings – The smaller thickness of the dielectric‐slab means the more conductive to transfer. The smaller radius of the via hole means the more conducive to transfer. The lower dielectric constant means the more conductive to transfer.
Research limitations/implications – Some boundary conditions such as perfect magnetic conduction (PMC) and perfect electric condition have not been studied, and only perfectly matched layer, which means the infinite plane is dealt with.
Practical implications – The transmission and reflection characteristic of via holes will contribute to the design in such fields: microwave planar circuits, multilayer printed circuit boards, radio frequency integrated circuits, monolithic microwave integrated circuits, etc. which can guarantee the maximum transmission and the minimum reflection or radiation.
Originality/value – This paper presents the transmission and reflection characteristic of via holes with different parameters by the MP‐MOM and the design of experimental test including de‐embedding method.
