Reflection and mutual coupling in a special kind of parallel-plate phased antenna arrays

An infinite phased antenna array ofplane parallel plate structures, where eveiy other structure is short circuited at a distance t from the aperture, has been investigated. In the analysis, a modal matching technique has been applied. It can be concluded that both reflection and mutual coupling can be reduced considerably by properly selecting the choke depth t and the material inside the plane parallel plate structures and the chokes (er)
