The modified feed is etched on a single-layered, 0.8 mm FR4 substrate. With the overall dipole length selected, the antenna can generate a fundamental (0.5wavelength) resonant mode at about 530 MHz to cover the lower-edge frequency (470 MHz) of the DTV band. However, to attain wideband operation and include the upper-edge frequency at 862 MHz, additional resonance is needed.
