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.
