To improve the radiation characteristics and the miniaturization of thin types of printed antennas, a miniaturized cross meander line antenna was developed. This antenna consists of two meander-lines etched on both surfaces of the dielectric substrate, where the line pattern on one surface was arranged by making a right-angled turn for that on the opposite surface. This antenna was measured and analyzed. According to the analyzed results, the return loss of this antenna was 17 dB and the antenna gain was larger than -30dBi in the center frequency at 298 MHz. The size of this antenna was 10 mm x 14 mm x 0.4 mm and it was considerably small and thin.
