Abstract
A simple and successful design for a small radar cross-section (RCS) and highly efficient waveguide slot antenna is presented. An artificial magnetic conductor and perfect electric conductor surface are combined together for RCS reduction and radiation improvement based on the principle of passive cancellation. A ring structure is first used in the waveguide slot antenna design. The novel antenna is compared with the traditional antenna and the results are better.Keywords
