This paper describes the design and simulation
of Sierpinski Carpet Fractal Planar Inverted F Antenna
(PIFA) for WLAN and HiperLAN applications. Simulation
of antenna is carried out using CST software; on a FR4
board with a substrate thickness of 1.6 mm and relative
permittivity of 4.7. The antenna achieved satisfactory 10-
dB impedance bandwidths, between the frequencies of
2341-2812 MHz and 5360-6154 MHz, which applies to
Bluetooth, WLAN and HiperLAN applications.
Performance of the proposed antenna is discussed in terms
of reflection coefficient (S11), radiation patterns, and gain.
Analysis of the result indicated that the number of
resonances increases linearly with the number of iteration.
On the other hand, bandwidth produced is also largest at
the highest resonance point. In the final design, the
proposed first fractal iteration produced the desirable
trade-off between bandwidth adequacy and resonating at
the desired frequencies.
