Abstract
This paper presents verification of multiband characteristics of a circularly shaped iterative fractal
antenna with increasing number of fractal iterations. The four numbers of iterations are considered for
this study. Also, the miniaturization characteristics of the fractal antenna with increasing number of
fractal iterations have been studied. The proposed 4
th iterated fractal antenna is designed on FR4
substrate (h = 1.56 mm and εr = 4.3). The antenna is coaxially fed using surface mount adapter. The
proposed circularly shaped fractal antenna is found to resonate at four centre frequencies such as 0.683
GHz, 0.97 GHz, 1.29 GHz, and 1.68 GHz. The antenna finds applications in various compact multiband
wireless communications due its smaller size , low cross polarization and multiband behaviour.
