ABSTRACT
Antenna scattering has been a complex problem due to the fact that reducing RCS of an antenna, especially when it is in radiating mode, would have adverse effect on its radiation performance. There are practical situations in aerospace/naval applications when the antenna/array RCS dominates over RCS of the platform over which it is mounted. Since radiation mode RCS is almost two orders of magnitude higher than its structural RCS, it is very important to control antenna scattering while it is radiating. The antenna mode RCS can be minimized in matched condition (in between radiating structure and its feed). However, it would lead to degradation in the antenna gain, especially at resonant frequency. The designs of different configurations of patch array discussed throughout the book demonstrate similar concepts. This chapter concludes the designs presented throughout the book.
