These will be examined from an array antenna perspective, and evaluated

The cavity resonator antenna (CRA) which is arguably better known as a partially reflective surface antenna (PRS) can be a source of very compact geometries. With its quite surprising potential for high dir

Compact Planar Reflectarrays,from the viewpoint of surfaces made periodic by slot patterns on plane surfaces, although physically many arrays of this genre appear more like patch based formations. Theoretically both slot and patch interpretations can be pursued in parallel since patch elements radiate through their edge-slots.

It provides the basic electromagnetic
