摘要：
A modified earpiece cord is proposed and evaluated as a wideband antenna for DVB-H reception. By winding the cord into a high-impedance from the impedance RF choke at one-quarter wavelength distance handset connection, a stable wideband input impedance is achieved. Using two-chip components for impedance matching. the complete UHF hand can be covered with > 35% antenna efficiency. Measured and simulated results are presented with good agreement.
