Excitation of Metal Plate Using Folded Dipole Antenna

抄録

In order to miniaturize an antenna mounted on mobile devices, the platform excitation has been studied. In this paper, the novel excitation method for the metal plate with 100 mm × 50 mm is proposed. For the platform excitation, characteristic mode analysis (CMA) is used to clarify the current distribution. The planar folded dipole antenna is employed to excite the current distributions on the metal plate which is obtained by CMA. We verify the validation of the proposed method by simulation and measurement. As a result, the measured results are in good agreement with the simulated results and the maximum actual gain of 4.3 dBi is obtained at 2.45 GHz.
