A Wideband DTV Antenna with a Multiple-Structure of Transmission Line Antenna

Abstract

The purpose of this work is to design a wideband DTV (Digital TV) antenna with a multiple-structure of transmission line antenna. A technique of varying the width of transmission line antenna is developed firstly to shorten its length. By adding three individual transmission line antenna with different bands together, a wideband characteristics is achieved in the UHF band. This is suitable for digital TV reception, especially for the DVB-T, which is based on the OFDM, because of its near omni-directional pattern.
