Abstract

A novel structure of tapered slotline antenna is presented. Using “palm tree” shaped metallization cross‐polarization levels are improved. Also their influence on 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 gain 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. © 2007 Wiley Periodicals, Inc.

A simple and compact coplanar waveguide to slotline transition operating from 22 to 34 GHz is presented. It is designed for feeding tapered slot antennas (TSAs) and has a slightly larger than usual output slotline width, which helps either to shorten the length or improve the gain of the TSA.
