  • Method for improving the efficiency of an electrically small antenna
    Patent number: 11050156
    Abstract: A method of improving the efficiency of an electrically small antenna (1), the method comprising the following steps: selecting (100) an antenna; electrically feeding said selected antenna (1); quantifying (110) the energy stored in the selected antenna (1) at a given transmission frequency; determining the nature of the antenna (1) as a function of the quantified stored energy, this determination comprising comparing (120) said quantity of stored energy with an energy threshold, the antenna (1) being of electric nature (130) if the quantified stored energy is below the energy threshold, and otherwise being of magnetic nature (135); and selecting a metamaterial inclusion (2) for associating with the selected antenna (1) in order to improve its efficiency, the selection being made from a list of inclusions as a function of the nature of the selected antenna (1).
