摘要: The design of a miniaturized CPW-fed ring slot antenna using interdigitated slits is presented. fundamental resonant frequency the was reduced significantly an slit-loaded structure. A further reduction in to 54.46% unloaded also achieved multiple inside ring, causing almost reach electrically small limit. Thereafter, characteristics enhanced low impedance metamaterial slab working under normal incidence, leading considerable superstrate height. Particularly, directivity and efficiency improved with incorporation low-profile superstrate. In addition, good matching are obtained for without necessity network together bandwidth.
