Abstract

The presence of surface waves different from the conventional grounded dielectric substrate surface wave modes, which can be excited on a finite periodic radiating array of printed dipoles, at frequencies for which the spacing between dipoles is typically less than half a wavelength is studied. The effects of such array guided surface waves on the array radiation characteristics are investigated. Techniques to suppress these surface waves are also discussed.
