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 × 1 mm 3 , much smaller than those reported antennas. The measured −10 dB bandwidth in the 2.44 GHz band is 140 MHz (2.37-2.51 GHz) and in 5.34 GHz is 1.23 GHz (4.86-6.09 GHz), covering the 2.4/5.2/5.8 GHz WLAN operating bands. Good radiations at these bands are also observed.
