Miniature microstrip antennas of very high permittivity materials (/spl epsiv//sub r/<35) have been fabricated, measured and analyzed by the FDTD method. Superstrates of appropriate thickness are added on the substrate for gain enhancement. Its size is dramatically reduced and the electrical performance remains comparable with the conventional microstrip antenna of low permittivity. The measured and computed results are in good agreement.
