Half Cylindrical Dielectric Resonator Antenna

Dielectric Resonator Antennas are becoming very attractive in many applications in today''s technology. This work emphasizes on the half cylindrical dielectric resonator antennas applied in the 5.2/5.8GHz WLAN. It also explains the principles of dielectric resonator antennas and offers a simplified theoretical understanding of the modes excited inside resonators with different shapes. Design principles are also explained. Some measured results are also included to give a better understanding to the practical limitations when designing such an antenna.
