Gantayet, Ajay and Rout, Debashis (2013) Design of Pentagonal Fractal Antenna for Ultra Wideband Applications. BTech thesis.
Ultra Wide band fractal antenna based on pentagonal geometry has been proposed in this thesis. Fractal shapes and their properties are discussed. The proposed antenna is microstrip line fed and its structure is based on fractal geometry where the resonance frequency of antenna is lowered by applying iteration techniques. Analysis of fractal antenna is done by using Software named CST Microwave Studio Suite 12. This antenna has low profile, is lightweight and easy to be fabricated and has successfully demonstrated multiband and broadband characteristics. The antenna size inclusive of the ground plane is compact with dimensions 7 X 7 cm2 and has wide operating bandwidths of 8 GHz. The antenna exhibits omnidirectional direction radiation coverage with a gain from 2 to 6.5 dBi in the entire operating band. Measured results show that this antenna operates from 4.7 to 12.7 GHz with a fractional bandwidth of above 90% and has relatively stable radiation patterns over its whole operation band.
