The authors propose a compact fractal antenna consisted of a Hilbert‐curve and self‐complementary configuration with dual‐band and circular polarization characteristics. This design merges the inductively loaded monopole antenna and the self‐complementary antenna to obtain a new monopole antenna. The self‐complementary Hilbert‐curve monopole antenna presents the desired bands of 2.43 GHz with bandwidth (BW) = 70 MHz (2.88%) and 5.35 GHz with BW = 550 MHz (10.36%). The circular polarizations for dual‐band are demonstrated with AR spectrum and orthogonal modes. The proposed antenna is successfully simulated and measured with frequency responses, radiation patterns, current distributions, and electric field intensities. © 2010 Wiley Periodicals, Inc.
