Abstract: An antenna structure comprises an unbalanced antenna for receiving digital video broadcasting signals. The antenna is dimensioned to fit within an electronic device, such as a mobile phone. The unbalanced antenna has a radiative element and a feed line connected to a matching circuit so as to achieve two or more resonances within a DVB-H frequency range, such as 470 to 702 MHz.

The resonators can be series or parallel connected between the feed line and RF circuitry for processing the broadcasting signals. The antenna can be tuned to other bands above the DVB-H frequencies for use as a diversity or MIMO antenna.

Abstract: A mobile communication terminal may be made smaller by using an internal antenna and a conductive layer. The conductive layer is spaced apart from the antenna by a fixed gap, and the conductive layer may be located either internally or externally to the terminal housing. The addition of the conductive layer provides a second resonant frequency in a higher frequency band than a first resonant frequency. Because the conductive layer has a relative smaller amount of radiation and is more directly affected by a human body than the internal antenna with a relatively larger amount of radiation, the performance characteristics of the terminal can be increased by a corresponding amount.
