In this presentation, a compact LHM unit cell, which smallest electrical size is only 0.1, is designed. The LHM unit cells are stacked and embedded into a host substrate to construct a phase-compensating substrate for the microstrip antenna (MSA) miniaturization. Results show that the presence of the LHM fillings can indeed greatly reduce the physical dimensions to 0.17 lambda. Moreover, a miniaturized...
In this letter, a further miniaturization approach for the exiting MCR design extending analysis to 3D isotropic case. It is shown that the subwavelength resonance occurs when transversal permeability components have opposite signs. In this case, the rectangular cavity supports subwavelength resonance, and the width and length of such the rectangular cavity resonator can be in principle simultaneously...
In this paper, an improved miniaturized cavity resonator (IMCR) dependent on double negative metamaterial (DNG) and epsilon-negative material (ENG) layers is designed and optimized. The length and width of the IMCR are simultaneously shortened to the half of a conventional cavity resonator. The IMCR is numerically simulated, results show that the resonance phenomenon in the IMCR is observed clearly,...
