研究目的
To solve the excitation and scattering problem for transverse circumferential slots in a shield of coaxial line with a dielectric insert just under the slot, determining internal conductivity including multiple reflections caused by the dielectric insert, and presenting formulas for radiation and reflection coefficients.
研究成果
A mathematical model of the system of circumferential slots in the shield of an inhomogeneous coaxial line with dielectric inserts is presented. Expressions for determining the main characteristics of single-slot and multi-slot antennas, including amplitude and phase distributions, radiation, reflection, and transmission coefficients, are obtained. This allows for the calculation of dependences from all antenna parameters and optimization of energy coefficients of this system.
研究不足
The study assumes the shield is infinitely thin and perfectly conductive, and the solution is correct only if there are loads on both sides of the slot, with the type of wave not changing after reflection. The methodology does not account for transformation of H- and E-types into other modes upon reflection from the boundaries of two dielectrics.
