An Accurate Circuit Model for Probe-fed CBS Antenna

摘要

An accurate lumped-element model for probe-fed CBS antenna has been presented in this paper. In this model, the probe-fed CBS antenna is separated into three parts: a coaxial line to rectangular waveguide transition, two rectangular waveguide transmission lines and a rectangular slot cut at the end of a rectangular waveguide. A C-band probe-fed CBS is designed using this model. The results agree well with the HFSS simulation results. Utilizing this model, the design procedure for probe-fed CBS can be fast and efficient.
