A novel low profile and dual-band antenna for terrestrial digital multimedia broadcasting (T-DMB) and ultra high frequency (UHF) applications is proposed in this paper. The proposed antenna consists of a folded inverted-L antenna and two open stubs. The designed low profile antenna occupies an antenna volume of 1484911 mm3. The length of the folded radiating element is about 0.09λ at the resonant frequency of T-DMB application (180-210 MHz). The parasitic open stubs are utilized to obtain the wide bandwidth (50%) for UHF application (470-740 MHz). The maximum gains at the frequencies of T-DMB and DTV applications were -5 and +5 dBi, respectively. The radiation patterns are near omni-directional at frequency of interest.

This paper briefly introduces the T-DMB standard based on Eureka-147 DAB and presents a new T-DMB transmission system, which uses a device called the Ensemble Remultiplexer, for mobile multimedia broadcasting service. And we verify the T-DMB standard by using the new transmission system with commercial equipment in the laboratory and in the field as moving on a car in high speed around urban districts surrounded by high buildings.
