Pseudo Fractal Tri-band Dipole Antenna For Mobile Wireless Sensors Networks

Abstract

In today's research of wireless communications, there is increasing need for more compact, multi-band and moderate gain antennas for communications systems, for either military or commercial communications systems. Fractal antenna designs can meet these design requirements. This paper introduces a novel small size and multi-band fractal dipole antenna called pseudo fractal antenna where H tree fractal together with Fibonacci sequence build the main antenna body and the expected result is a tri-band antenna with resonance frequencies in the ISM bands 915MHz, 2450MHz and the 5800MHz. The performances of this pseudo fractal antenna were numerically analyzed with NEC2D professional software.
