Several ultrawide band (UWB, 3.1–10.6 GHz) antennas are presented for either wireless communications or detection applications. An UWB antenna could be either a planer structure for portable devices or has a 3D configuration, which is suitable for an access point. Dielectric resonator is used to tremendously shrink an UWB antenna's size, which is important for a terminal device. Different DR loading...
Two novel UWB dielectric resonator antennas (DRA) are designed for broadside radiation and Omni-directional radiation. The dielectric resonator (DR) is mounted on a vertical ground plane edge, which is printed on a thin dielectric substrate. The DR is inserted it in the dielectric substrate by cutting it to fit the dielectric resonator. For the broadside type, the deformation of the radiation patterns...
