Abstract
A broadband printed dipole antenna capable of generating a wide operating band for digital television signal reception in the 470-806 MHz band is presented. The antenna is of a rectangular shape of width 20 mm and length 227 mm , and comprises two asymmetric radiating portions of arm 1 and arm 2 separated by a step-shaped feed gap with its one open end at the center of antenna's one long side edge and the other open end at about /4 away from the center of the opposite long side edge. The antenna can generate two adjacent resonant modes to form a wide operating band of larger than 50% in 2.5:1 VSWR bandwidth, which is much wider than that of the corresponding conventional center-fed dipole antenna.
