Planar antennas fed by electromagnetically coupled coplanar waveguide (CPW) have been fabricated on a single layer substrate with various thicknesses, and been studied experimentally. To suppress the spurious mode due to the parallel plate structure in the antenna system, short pins are inserted near the feeding point of the coplanar line. The measurement results of this antenna demonstrated high performance in both return loss and radiation pattern.
