Abstract

This paper considers the design and manufacture, using stacked rings, of a standard corrugated antenna for the WM-380 band for use as a converter from a WM-380 rectangular aperture to a large diameter conical corrugated waveguide. In-house mode matching software is utilised for the design and three prototypes manufactured using stacked rings. The level of agreement of the stacked ring prototypes with the design predictions for the return loss and HE11 modal coupling is measured and found to demonstrate high levels of agreement.
