Abstract :
The reconfigurable antenna is a revolutionary new type of antenna that controls the radiation pattern by dynamically adjusting its aperture. It provides a unique way to cover different frequency bands and, in an array, provides a beam steering capability. There is therefore a great demand for reconfigurable antennas in the field of wireless communications, satellite communications, radar etc. We present a reconfigurable Yagi to work at both the 5.78 GHz and 2.4 GHz frequencies. It is intended for use in the transition period when wireless communication shifts to the 5.78 GHz band. Preliminary results for this reconfigurable antenna are presented.
