Genetic Algorithm Based Approach for Frequency Switchable Dual-Band Patch Antenna

Blog Article

In this paper, a frequency switchable antenna design using genetic algorithms (GAs) for dual band WiMAX (3.5GHz) and WLAN (5.2GHz) applications is proposed.The area of the radiating patch element is divided into 2 mm square cells, with azalea southern charm each cell assigned a conducting or non-conducting characteristic.To realize frequency reconfiguration, switches are incorporated into appropriate locations to activate/deactivate corresponding cells.

The on/off states of the switches are represented by the presence or absence of conductor, respectively.Hence, the proposed approach allows the antenna to operate as mono-band or rusk 6.66rr dual-band radiator according to the desired application.Further, measurements and simulations are carried out and a reasonable agreement is achieved.
