Summary :

A radial line slot antenna (RLSA) is a high gain and high efficiency planar antenna for DBS reception and VSAT terminals. To generalize the slot design of RLSA, it is necessary to estimate the radiation, reflection and the transmission characteristics of a slot. This paper presents an equivalent circuit of a slot on radial waveguide. A periodic structure model is used in the moment method analysis, to simulate the slot coupling in rotationally symmetric antenna operation in the oversized radial line. Radiation and reflection coefficients are expressed in the S-matrix form; the slot length dependence of the matrix element is discussed.
