ABSTRACT: A new technique which is a combination of fractal antenna and array antenna is presented
to design Plus Slotted Fractal Antenna Array (PSFAA) in this paper. PSFAA
with corporate feed operates at 2.5 GHz frequency. PSFAA is designed on FR4 substrate
material with permittivity 4.4 and height 1.6 mm. PSFAA is designed up to 2nd
iteration. High Frequency Structure Simulator (HFSS) software is used for simulation
of PSFAA. The proposed antenna array operates at three bands with five frequencies
2.5 GHz, 4.1 GHz, 6.9 GHz, 7.4 GHz and 8.2 GHz. Simulated Return losses
results of proposed PSFAA are -22.15 dB, -19.44 dB, -25.21 dB, -10 dB, -12.45 dB
at above frequencies respectively. It has a gain of 9.22 dB at resonant frequency 2.5
GHz whereas conventional antenna array has a gain of 5.15 dB at resonant frequency
2.5 GHz. Return losses and gain of PSFAA also improved from conventional antenna
array at various resonant frequencies.
