Abstract :
A novel Dipole-Yagi antenna is presented with frequency reconfigurable capability. The novel structure is based from Yagi-Uda antenna, consist of dipole as a main radiator and four parasitic metal strips. The parasitic metal strips can be formed to function as part of the radiator, reflector or director by means of switches. The switches are located at specific position. Four switched band at 0.98, 1.5, 2.1 and 2.5 GHz are demonstrated. Measured and simulated results are presented. Good agreement is observed.
