Abstract :
Based on the narrow-slit fractal method, a novel compact square microstrip fractal antenna with symmetrical T-slits to achieve circular polarization (CP) operation is proposed. By introducing two pairs of symmetrical T-slits, high cross-polarization is effectively suppressed. In addition, a patch size reduction as large as ~34.3% for the proposed antenna, compared to the conventional regular-size CP antenna without the symmetrical slits, has been obtained.
