In this paper the design, fabrication, and testing of a miniaturized rectangular microstrip patch antenna loaded with DNG metamaterials is reported. The metamaterial is composed of two nested spiral strips and a single straight strip which are etched on two sides of a 5.7 mm×5.7 mm Rogers RT/duroid 5880 with 0.5 mm thickness and dielectric constant of 2.2. Two units of this structure as a doubl...

The compact rectangular microstrip antenna is realized by placing the shorting post or plate along the zero field line at the fundamental mode of the patch. The dual band antenna is realized by placing the stub on the edges of the patch. In this paper, first a compact shorted rectangular microstrip antenna is discussed. Further a dual band antenna realized by placing the stub on the opposite ed...
