Abstract

Abstract : A wideband slot array antenna fed by perfect magnetic conductor (PMC) packaged microstrip lines at 28 GHz frequency range is presented. The slot array is designed with conventional microstrip technology and a PMC layer is used as a packaging solution to stop surface waves, cavity modes or any unwanted field leakage, coupling or radiation from the feeding lines. The PMC is implemented with a periodic metal pin structure. The array is fed by a corporate feed system and a good agreement with experimental results is obtained.
