Abstract: Hexagonal patch antenna with coplanar wave guide (CPW) feed working with in ultra wide band (UWB) range. Its hexagonal aperture is altered to spiral fork shaped then resultant structure is producing triple bands at 1.36GHz, 5.74GHz and 8.8GHz. When ground of basic antenna is altered then resultant structure is producing penta bands at 2.38GHz, 3.64GHz, 6.76GHz, 7.36GHz and 8.98GHz. Corresponding impedance band widths are 200MHz, 70MHz, 170MHz, 520MHz and 420MHz and peak gains are 1.77dB, 2.45db, 3.53dB, 4.54dB and 2.28dB respectively. These antennas are suitable for S – , C – and X – band applications
