Abstruct-The design of coplanar waveguide (CPW)-fed bow-tie antenna for the 2.4-GHz ISM band is described in this letter. A coplanar waveguide-to-coplanar strips (CPW-to-CPS) balun is used to obtain the balanced feed line for the printed bow tie. Analysis method based on the mixed potential integral equation method is used to characterize the input characteristics of the bow-tie antenna. Obtained numerical results are in good agreement with experimental data. Through experiments with bowtie
