Abstract :
In this paper, the optically transparent microstrip antenna made of transparent ITO (Indium Tin Oxide) films is investigated. The present transparent microstrip antenna comprises a thin sheet of quartz glass substrate with two conductive ITO film coatings and is fed through a coaxial probe. As an example, an X-band transparent microstrip antenna is designed, fabricated and measured. To discuss the effect of electromagnetic leakage of ITO film on the radiation efficiency, two rectangle cavity resonators with same dimensions are analyzed. The boundary conditions of the two resonators are the same except the top layers of one is copper while the other is ITO film with sheet resistance of 3Ω/sq.
