Abstract
An ultra-compact dual-band printed antenna is proposed. Connective and concentric double split rings (CCDSR) are used to generate two resonant frequencies in wireless local area network (WLAN) frequency bands. Tuning arms are added to the microstrip fed line, which can be used to tune the upper frequency band. The dimension of this antenna is only 9×24×1mm3, much smaller than those reported antennas. The measured -10 dB bandwidth in the 2.44GHz band is 140MHz (2.37-2.51GHz) and in 5.34GHz is 1.23GHz (4.86-6.09GHz), covering the 2.4/5.2/5.8GHz WLAN operating bands. Good radiations at these bands are also observed.
