Calculation of the dispersion diagram for planar electromagnetic bandgap structures
(2008)2008 IEEE Antennas and Propagation Society International SymposiumThis paper presents a numerical technique for the accurate calculation of the dispersion diagram of planar electromagnetic bandgap structures. The method is based on coupling the energy of an incident plane-wave in a perturbed structure, which has the same resonance frequencies, and studying the reflection spectra form the structure. In this method, solving the dispersion problem is transformed to solving a diffraction problem accompanied ...Conference Paper -
Simulation and experimental investigation of the radiation efficiency of a dielectric resonator antenna
(2008)2008 IEEE Antennas and Propagation Society International SymposiumIn this paper, we attempt to get a deeper insight into the radiation efficiency of the DRA and the difference of accuracy between the D/G method and the Wheeler cap method by measuring a simple rectangular DRA at C band with both methods. It is, on one hand, confirmed that, the radiation efficiency of the DRA can be as high as 98% at C band. On the other hand, the comparison of the two efficiency measurement methods shows discrepancies ...Conference Paper -
