Abstract

In this paper, two Sierpinski carpet UWB fractal antennas are designed and fabricated. The first fractal antenna is an antenna that has not any notch filter. The second one is an antenna with double notch filters. Antenna without notch filter has an operating band of (3.1–10.8) GHz with a gain of 5.3 dB at 10 GHz. This antenna has a low group delay variation. Antenna with double notch filters working at (3.36–12) GHz band shows a gain reduction and higher group delay at the filters operating band. Out of the notch filters operating band, the antenna has a low group delay variation and a gain near to the gain of the antenna without notch filters. The MIMO version of the antenna shows an operating band up to 10.8 GHz and isolation between ports higher than 15 dB.
