In this article, an ultrawide band inscribed triangle circular fractal antenna is presented. The antenna has been designed on FR4 substrate dielectric constant ɛr=4.3 and thickness of substrate 1.53mm with initial dimension of 30mm diameter. The experimental result of fractal antenna exhibits the excellent ultra bandwidth from 2.25GHz to 15GHz corresponds to 147.83% impedance bandwidth at VSWR 2:1. This ultrawide band characteristcs of antenna has been achieved by using the CPW-fed and fractal concept. The measured radiation pattern of fractal antenna is nealy omnidirectional in azimuth plane and bidirectional in elevation plane. The measured group delay of proposed antenna is…
