Definitions

  • the present disclosure relates to the field of antenna technique and particularly to an antenna assembly for a mobile terminal.
  • a mobile terminal has increasingly complicated functions and has to comply with a variety of communication protocols and standards while its figure being increasingly miniaturized and ultra-thinned. These trends result in an increasingly small space available for an antenna element in the mobile terminal on one hand and an increasing demand for the performance of the antenna which only occupies a limited space on the other hand. That is to say, an antenna system has to operate with good performance in more frequency bands or at a higher bandwidth.
  • the radiation performance of the antenna which is a frequency-dependent element is proportionate to the size of the space occupied by the antenna.
