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,...
Here a miniaturized microstrip antenna is under consideration which is loaded by a pair of traditional double positive (DPS) substrate and practically dispersive double negative (DNG) substrate. This paper investigates the possibility and ability of microstrip antenna miniaturization with practically dispersive DNG medium. The practically dispersive DNG medium is synthesized based on the traditional...
