Abstract
A novel dual band antenna for DVB-H (Digital Video Broadcasting-Handheld) and T-DMB (Terrestrial Digital Multimedia Broadcasting) services are presented. By adjusting the gap distance between the long and short bar-shape metal plates, wide and dual band properties are achieved. The proposed antenna shows good impedance and radiation characteristics for DVB-H band (470 MHz to 870 MHz) and T-DMB band (1.45 GHz to 1.48 GHz). The measured return losses over the frequency band of interest are better than −10 dB. In addition, good radiation patterns are also obtained. The measured results are compared with calculated results using Ansoft HFSS (High Frequency Structure Simulator).
