Abstract
In this paper, a design method for a compact broadband planar monopole antenna fed by a coplanar waveguide (CPW) is studied. The proposed broadband monopole is optimized for terrestrial digital television (DTV) reception. In order to achieve broadband characteristics, the monopole and ground conductor are gradually tapered. By loading slit pairs on both monopole and ground plane, the proposed antenna is miniaturized. The monopole is fed by a CPW with 75-ohm characteristic impedance on an FR4 substrate and its size is $100mm{\times}200mm$. 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.
