Fractal monopole‐like antenna with series Hilbert‐curves for WLAN dual‐band and circular polarization applications

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.
