Definitions

  • the quarter-wave support due to the quarter-wave support, the currents induced on the housing by the antenna are almost zero. In fact, the support having a quarter-wavelength length acts as quarter-wave hatch. The indirect radiation induced by the antenna in the user's head, by the intermediary of the case, is therefore also reduced. The invention thus makes it possible to limit the proportion of electromagnetic radiation due to the housing, and which would be lost in the user's head.
