In this Letter, a Koch slot loop in the ground plane has been utilized to obtain slow-wave characteristics, and its electrical performances are analyzed with the use of the ABCD matrix approach. The validity of this approach has been verified through experimental results, and this technique was then applied to microstrip patch antennas in order to obtain a small antenna size. The cross-sectional areas of this type of antenna are 47% to 65% smaller than those of conventional square patches.
