Impedance bandwidth optimization of double slots circular patch antenna using genetic algorithm and the Interface Fuzzy Logic
Research Paper
Research Paper
A modified circular patch antenna design has been proposed in this paper, the
bandwidth of this antenna is optimized using the genetic algorithm (GA) based on fuzzy
decision-making. This design is simulated with HP HFSS Program that based on finite element
method. This method is employed for analysis at the frequency band of 1.4 GHz- 2.6 GHz. It
gives good impedance bandwidth of the order of 15.5% at the frequency band of 1.67GHz-
1.95GHz and 10.6% at 2.23GHz- 2.48GHz. It means that impedance bandwidth increases above
4.9% than the impedance bandwidth of ordinary circular patch antennas and band width rise
from 1.78GHz- 1.98GHz (10.6%) to 1.67GHz- 1.95GHz (15.5%) and 2.23GHz- 2.48GHz
(10.6%). The antenna fabricated with two slots on circular patch antenna. The measured results
of the optimized antenna validate a high compatibility between the simulation and the
measurements.
