Abstract
In this paper, we proposed and fabricated the single-feed dual-band circular patch antenna for S-DMB(Satellite-Digital Multimedia Broadcasting) and ITS(Intelligent Transport Systems) services. The manufactured dual-band antenna showed that the measured -10 dB bandwidth and the minimum return loss was 90 MHz and -35 dB for S-DMB, 180 MHz and -18 dB for ITS, respectively. It is noticed that the measured and the simulated results are agreed well. And the antenna gain of S-DMB and ITS has 2.3 dBi and 2.7 dBi, respectively.
