Abstract

To miniaturize thin types of printed antennas, a bilaterally-etched cross meander-line antenna was developed for specified low-power radio applications at 300 MHz. This antenna consists of two meander-line patterns etched on both surfaces of a dielectric substrate, where the meander-line patterns were crossed each other. According to analytical results, the return loss of this antenna was 17 dB and the antenna gain was -30 dBi at center frequency of 298 MHz. This antenna was considerably small and thin because it was etched on a glass-Teflon substrate, having an area of 10 mm times 14 mm and a thickness of 0.2 mm.
