A miniaturized planar digital video broadcasting terrestrial (DVB‐T) antenna, which is composed of a patterned helical line, an open stub, and an impedance matching circuit on an FR4 (ɛ r =4.4) substrate for portable media player applications, is presented in this letter. The antenna has monopole‐like, omni‐directional radiation characteristics and a wide impedance bandwidth (VSWR<3) in the DVB‐T band from 174 MHz to 230 MHz at the VHF band.
