Abstract. Frequency and radiation characteristics of conductive ink-based antennas printed on a paper sheet and a polyimide film are investigated. The sizes of antennas are selected such that the working frequency range is between 2 and 3 GHz. The study includes modeling and testing of several antenna samples on both substrate types. It is shown that the radiation efficiency of antennas printed by conductive ink with the thickness of the ink layer around 0.5 micron on the polyimide film is comparable with the radiation efficiency of an antenna made from a copper foil of the same size on the same substrate. However the efficiency of printed ink antennas on the paper substrate turned out to be rather low because of higher ohm losses in the printed conductors. The simulated and measured matching characteristics correspond to each other fairly well for all tested samples. It is concluded that further development and applications are very promising.
