A simulation of frequency reconfigurable antenna is presented. The antenna is an integration of wide band monopole antenna with a microstrip slot antenna. It has a capability to operate in wide band (1.85 -7.18 GHz) and narrow band (5.29 GHz). 3 switches are used to select between wide and narrow bands. The proposed antenna demonstrates frequency agility which useful for future communication systems such as cognitive radios.
