Abstract

This article presents a coplanar printed monopole antenna for digital television (DTV) in the UHF band (470-862 MHz) application. The antenna structure consists of a meander loop monopole for radiation, a step-shaped ground plane for impedance matching, and a 50-mini coaxial feedline for excitation. The meander loop monopole and step-shaped ground plane are printed on the same side of a substrate with an area of 15×170 mm². The measured impedance bandwidth for 2.5:1 voltage standing wave ratio (VSWR) is 550 MHz (465-1015 MHz, 74%), covering the DTV band. In addition, the proposed antenna shows a real reception performance on a notebook computer. The reception results for audio and video signals exhibit stable characteristics.
