A dielectric protecting superstate with spacing on the order of one wavelength from the rectangular microstrip patch antenna and of thickness up to about half a wavelength shows very small variation in resonance frequency (f r ) and reflection coefficient (Γ). Effects of the same on radiation pattern (RP) includes drastic changes in beamwidths. By use of the spaced superstate the patch can be protected without the need to redesign parameters like f r and Γ. © 1994 John Wiley & Sons, Inc.
