摘要：

A novel structure of tapered slotline antenna is presented. Using '' palm tree '' shaped metallization cross-polarization levels are improved. Also their influence oil radiation pattern is considered. Matching performance is at least as good as a simple exponential tapered slotline (Vivaldi) antenna. Frequency coverage for return loss < - 10 dB exceeded 5.5:1 (2.9-15 GHz) and measured reached values higher than 6 dB from 5 to 15 GHz. Radiation pattern is stable from 6 GHz to 12 GHz and cross-polarization is below -20 dB for the 3-11 GHz band in the main direction. (c) 2007 Wiley Periodicals. Inc.
