A novel design of fractal monopole‐like antenna with series Hilbert‐curve configuration is proposed for 2.45/5.35 GHz dual‐band and circular polarization applications in this article. The compact fractal antenna consists of five series Hilbert‐curve and the monopole couplings, and exhibits the desired dual‐band 2.45 GHz (BW = 85 MHz, 3.45%) and 5.35 GHz (BW = 240 MHz, 4.46%), respectively, for IEEE 802.11a/b/g WLAN applications. The circular polarizations for dual‐band are demonstrated with AR spectrum and electric field intensities. Results included with frequency responses, radiation patterns, and electric field intensities are presented and discussed. © 2009 Wiley Periodicals, Inc.
