Optimisation of a PIFA Antenna Using Genetic Algorithms
نویسندگان
چکیده
This work presents the optimisation of PIFA (Planar Inverted-F Antenna) antennas in order to achieve a large bandwidth in the 2 GHz band, using an optimisation technique based on genetic algorithms. During the optimisation process, the different antenna models have been evaluated using the finite-difference time domain (FDTD) method. As a result of this optimisation, a simple PIFA antenna was obtained with a bandwidth of 460MHz and an even greater bandwidth of 570MHz was achieved with a double PIFA antenna with the same overall dimensions.
