Abstract :
A miniaturized printed fractal-rhombus slot antenna is proposed for the circular polarization (CP) operation by using an L-shaped feed. Experimental results shows that the measured impedance bandwidth (RL ≤ -10dB) is 29.4%(3.74 GHz-5.03 GHz) and the 3dB axial-ratio bandwidth reaches 16.9 %(3.8 GHz-4.5 GHz). The overall size of the antenna is only 40mm×40mm× 0.762mm. The proposed technology is attractive for designing low-cost, compact, broadband circularly-polarized antennas and arrays.
