Compact Dipole Antenna for Terrestrial Digital Multimedia Broadcasting Service

Rapid progress in TV broadcasting technology offers high quality broadcasting services for portable devices, such as the mobile phone, electronic notebook, and PDA. In particular, Terrestrial Digital Multimedia Broadcasting (TDMB) service was initiated for various mobile devices in Korea. TDMB can provide seamless high-quality audio, video, and data services. Since the wavelength at the center frequency (190 MHz) of band-III (174 MHz to 216 MHz) TDMB service is 1.5 m, an ordinary dipole antenna is too long to use for portable devices. In this paper, a compact dipole design for a TDMB antenna is proposed. The proposed antenna consists of a meandered pattern and lumped elements.
