MULTIBAND FRACTAL ANTENNA WITH DIFFERENT GEOMETRIES FOR WIRELESS COMMUNICATION

This paper presents multiband antennae loaded with different fractal geometries and compares their return losses. The first design of the antenna introduces three iterations of the fractal geometry which show multiband behavior for second iteration. The third iteration shows that antenna works in frequency range of 2 GHz up to 9.3 GHz and thus showing increased bandwidth. The second design introduces a fractal antenna with combination of four fractal geometry from the first design, showing further increased bandwidth and antenna working in frequency range of 3.1 GHz to 10.6 GHz. All the results have been demonstrated successively using simulation whereby all results satisfy the performance under -10dB point. These antennae can be used for WLAN, hyper LAN (High Frequency Radio LAN), satellite communication and radar imaging in the wide frequency band of 1-10 GHz.
