Design of Pentagonal Fractal Antenna for Ultra Wideband Applications

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