A novel conical dielectric resonator antenna (DRA) with tunable radiation pattern has been proposed. The antenna adopts one type of conical dielectric resonator (DR) and arc-shaped coplanar waveguide ground, which has the potential to achieve wideband characteristic. The operating frequency range of the antenna is 1550MHz (8.96–10.51 GHz) or 1340MHz (9.53–10.87 GHz). Some parasitic elements with two...
On the basis of previous theoretical and experimental investigation there proposed and described the technical decision about examined possibility to do the receiver-frequency-meter-tuner of generators on the Josephson junctions (JJ) working in super wide band. It can be especially convenient for the experimental purposes with new generation structures when radiate power is small and frequency are...
A dual-band conical dielectric resonator antenna with circular patch feed has been presented in this paper. Using conical dielectric resonator, the resonance frequency of monopole can be reduced contributing to antenna miniaturization, and high-order hybrid mode resonance can be achieved for another operating band. The circular patch fed by coaxial line performs the functions of the feeding structure...
A dual-polarized conical dielectric resonator antenna with hybrid feed mechanism is presented. The design for the proposed antenna excitation structure consists of slot fed by a microstrip line and a coplanar waveguide (CPW), providing the orthogonal polarizations. Dual-polarization can be well matched with the common −10dB impedance bandwidth of 1180MHz (24.4%). The overall dimension of the proposed...
A novel dielectric resonator antenna with an ultra-wideband (UWB) bandwidth and great time-domain performances has been proposed. The proposed feed for cone dielectric resonator antenna is a circular patch, which has the potential to achieve ultra-wideband characteristic. The operating frequency range of the antenna is 2.77–11.63GHz. The design provides constant group delay, consistent omni-directional...
