Design and Fabrication of a Frequency Reconfigurable Printed Antenna

摘要

This paper presents a frequency reconfigurable printed antenna that switches between two different operating modes according to the state of the switch element, for the OFF state of the switch, the antenna operates in the S frequency band at 3 GHz (2.65 - 3.66 GHz) covers the weather radar and satellite applications, when the switch is in the ON state the antenna operates in two frequency bands simultaneously at 2.45 GHz (2.20 - 2.76 GHz) and 5.4 GHz (5.36 - 5.76 GHz) for the WIFI and WLAN applications respectively. The simulation step is done using CST MWS, the fabricated antenna is tested in the laboratory in order to validate the simulation results.
