Abstract
The object of this chapter is to present some calculations on the coupling and directivity of a number of cross-guide couplers in a ridge waveguide. The four possibilities consist of one arrangement with both the primary and secondary waveguides in a double ridge, a similar arrange ment with primary and secondary waveguides in a single ridge, and configurations with the primary and secondary waveguides in either single and double ridge or double and single ridge, respectively. The coupling geometry usually consists of either a circular or cross-slot aperture. Apart from discrepancies in the vicinity of the ridge discontinuities these agree well with some Finite Element Method (FEM) calculations in the same chapter. The closed-form formulations may therefore be utilised for engineering purposes.
