The present letter concerns the reduction of the global size of a patch ant
enna by the insertion of printed inductive elements. A transmission-line mo
del is established to relate to the TM100 mode and support the different el
aborations of the reduced patch. The global reduction can reach 50% of the
initial size. Along with the theory, a set of experiments have been made to
validate the approach. (C) 2001. John Wiley & Sons, Inc.
