Abstract
AbstractThis article presents design of Appollian‐like gasket CPW‐fed fractal antenna. The antenna has been designed on FR4 substrate, εr = 4.3, with a thickness of 1.53 mm. The antenna has been fabricated and tested using VNA. The experimental result of this antenna shows the multiband behavior with the centre frequencies of 1.265, 4.66, and 7.8 GHz with impedance bandwidth of 50%, 17.5%, and 15%, respectively. The shift in first resonant frequency of antenna reveals the size reduction in comparison of solid equilateral triangular patch of 40 mm. The experimental radiation pattern of the antenna has been observed near to omnidirectional at lower frequency and like electric dipole antenna at higher frequency. This antenna can be used for short range wireless applications. © 2009 Wiley Periodicals, Inc.
