摘要Abstract: In this paper,a novel and simple type of CPW-fed dual-frequency monopole antenna is proposed. The most CPW antenna was designed on the FR4 substrate (εr=4.2) and it would take a larger area. For
the purpose of miniaturization, Al2O3 ceramics with the higher dielectric constant of εr=9.8 were used as the substrates of the designed antennas. Because of high quality factor (Q×f=300,000, the Al2O3 ceramics is hard to design the high bandwidth (BW, -10 dB measured from the return loss (S11) value) and with high S11 value, and that let the antenna is suitable for the applications of wireless local area network (WLAN) IEEE 802.11b/g (2400~2484 MHz) and IEEE 802.11a (5150~5350 MHz).
