    Abstract:

    A miniaturized Antipodal Vivaldi Antennas(AVA) with loading director is proposed. Compared with most of the antipodal Vivaldi antennas, the proposed antenna has a very small size which is only 14 mm×34 mm×0.8 mm. The director is provided with a triangle and placed between the openings of the antenna. It guides electromagnetic waves emitting from the aperture of the antenna to the edge of the conductive director with a smaller reflection and better transmission characteristics compared to that of the traditional AVAs. In addition, in order to reduce the measurement error, the antenna is combined with the Sub Miniature A(SMA) head. The results show that the antenna has a wide bandwidth from 5.2 to 11 GHz for S11<-10 dB, and the peak gain of the antenna is apparently increased in the range of 8.5-11 GHz, which validates the feasibility of this novel design.
