Abstract :
A novel triple-band antenna for the terrestrial digital multimedia broadcasting (T-DMB), digital video broadcasting handheld (DVB-H) and digital audio broadcasting (DAB) services are presented. By using the simple structure of two bar-shaped radiators with spiral ring shaped parasitic patches, meandered structures and lumped elements on FR4 substrate, triple-band performance and compact size are achieved. The designed antenna has good impedance matching and radiation characteristics for T-DMB band-III (174 MHz~216 MHz) band, DAB L-band (1.45 GHz~1.48 GHz) band and DVB-H band (470 MHz~870 MHz). Details of the antenna design as well as antenna characteristics are presented.
