SLOT ANTENNA FED BY A CPW LINE WITH TAPERED TRANSITION

A tapered coplanar waveguide (CPW) transition is pro- posed 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 50 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 pur- poses. The tapered transition proposed here results in a negligible re-
