Abstract
A tapered coplanar waveguide (CPW) transition is proposed in order to facilitate the connection between a slot antenna and coaxial connector. The broadband bow‐tie slot antenna is considered as an example in this design. The tapered transition is utilized to optimize the connection of two 50Ω CPW lines with different widths. A narrow CPW line is connected to the slot‐antenna feed point and the wide CPW line is connected to the coaxial SMA connector for measurement purposes. The tapered transition proposed here results in a negligible reflection in the CPW feed when its length is approximately λ/20. © 2003 Wiley Periodicals, Inc.
