Abstract
A microwave lens of Rotman type, to be used in a broadband multibeam antenna, has been designed in microstrip technology. The method of analysis used, based on a ray approach, is briefly described and compared for a circular geometry with a, in some respect, rigorous method. The design of a Rotman lens with 15 beam ports and 15 antenna element ports is described as are the measured and calculated transmission through the lens and the arrayfactor as calculated from the measured transmission coefficients.
