Monopole Antenna Design Using a Genetic Algorithm with Dual-Band and Wideband Operations

A novel dual-band design of a microstrip-fed monopole antenna designed by double population genetic algorithm (DPGA) is proposed. The antenna is analyzed by using the finite-difference time-domain (FDTD) method. The simulated results by CST MWS show good dual-band operation, with impedance bandwidths of 2.13-2.9 GHz and 4.17-7.05 GHz, respectively, suitable for applications to the 2.4/5.2/5.8-GHz WLAN communication systems. In addition, similar monopole-like radiation patterns and antenna gains over the operating bands have been obtained.
