ABSTRACT A compact design of a circularly-polarized (CP) antenna to achieve wide-band behavior for Wi- Max applications is presented. Single feed is used to excite a single-layered square patch integrated with a novel Y-shaped slot and two different truncated corners to achieve CP polarization. Besides its structural simplicity, ease of fabrication and low cost, the […]

ABSTRACT Using a vacuumed spray method, Zinc Oxide has been synthesized in a vacuum at a room temperature with different thicknesses. Absorbance and transparency have been studied as a function of wavelength variation before and after annealing the samples. Peaks have occurred at different wavelengths. Energy gap variation of the same samples has been examined […]
