In this paper, a design method for a compact broadband planar monopole antenna fed by coplanar waveguide (CPW) is studied. The proposed broadband monopole is optimized for terrestrial digital television (DTV) receiving. The monopole is fed by a CPW with 75-ohm characteristic impedance on an FR4 substrate and its size is $100mm{\times}200mm$. A pair of slit is appended for size reduction and an inductive stub is loaded for the impedance matching between the feedline and monopole. The optimized monopole antenna for DTV band (470-806 MHz) is fabricated on an FR4 substrate and tested experimentally to verify the results of this study.
