Abstract
A dielectric protecting superstrate with spacing on the order of one w avelength from the rectangular microstrip patch antenna and of thickne ss up to about half a wavelength shows very small variation in resonan ce frequency (f(r) and reflection coefficient (GAMMA). Effects of the same on radiation pattern (RP) includes drastic changes in beamwidths. By use of the spaced superstrate the patch can be protected without t he need to redesign parameters like f(r) and GAMMA. (C) 1994 John Wile y & Sons, Inc.
