The design of a printed slot antenna with dual‐band circular polarization (CP) characteristic is presented. The proposed antenna is excited by an L‐shaped strip with a taper end, connected in series to a microstrip‐line‐fed located along the diagonal line of the square‐slot. Wide impedance and 3 dB axial‐ratio bandwidth (CP bandwidth) are measured and the proposed design is suitable for 802.11 a/b/g and WCDMA operations. © 2008 Wiley Periodicals, Inc.
