چکیده
A multiband magneto-dielectric resonator antenna with cylindrical geometry is proposed in this paper. The composed of yttrium iron garnet (YIG) chemical composition Y3Fe2(FeO4)3. final structure built on a low-cost FR4 dielectric substrate. With only one resonator, the able to resonate three distinct controlled frequency bands. These are propagation modes HEM11δ, TE01δ, and TM01δ, which possible be independently at each input port antenna. resonator’s was suitable designed feed specific using microstrip lines placed judiciously excite mode. Analytic, numerical, experimental studies were performed and, after optimization, design obtained. obtained simulated measured S-parameters results below -10 dB resonance frequencies 5.75 GHz, 6.86 8.37 GHz. corresponding bandwidths 370 MHz, 120 1060 respectively. has total size 32.5 × 8.35 mm3. Measured radiation patterns gain also presented show good agreement when compared results.

Abstract—A new wideband and high-gain dielectric resonator antenna (DRA) is proposed. Three cylindrical dielectric resonators (DRs) with different materials and different sizes and a metallic cylinder are designed to obtain a wideband bandwidth and a high gain. The stacked structure provides a wideband bandwidth, and the cavity formed by the metallic cylinder provides a high gain. The measured ...
متن کاملTunable Dielectric Resonator-Based Left-Handed Leaky Wave Antenna
Recently, left-handed (LH) metamaterials have been achieved by arranging an array of TE resonant dielectric resonators (DRs) in a cut-off parallel plate waveguide [1], [2]. Since negative permittivity is provided by the TE cut-off background, the DRs only need to generate the required negative permeability in order to realize a LH metamaterial. This configuration provides a more flexible choice...
