研究目的
To characterize an anisotropic dielectric resonator antenna (ADRA) with uniaxial and biaxial permittivity tensors using the dielectric waveguide model, derive an approximate formula for the Q factor of ADRA, and demonstrate the design of a wideband ADRA under certain conditions.
研究成果
The uniaxially anisotropic rectangular dielectric resonator antenna (ADRA) is fully investigated in this paper. It has been found that the impedance bandwidth of the ADRA is improved compared to the isotropic DRA. The theoretical investigations on impedance bandwidth of ADRA are carried out. The theoretical results reported here are useful in the design and understanding of ADRA.
研究不足
The study is limited to the analysis and simulation of uniaxial and biaxial anisotropic dielectric resonator antennas. The practical implementation and testing of these antennas are not covered in this paper.
