Text 1935 111 22 #000000 0 first step: \n For the Poller measurement antennas shall be placed in nominal charging position and application specific setting, Listener antenna open.  \n Repeat for Listener same way.  \n Then short one antenna and measure parameters. With this coupling factor can be also calculated. \n  \n second step: \n Insert measured/simulated antenna parameters (Poller impedance and Listener impedance);  \n set coupling factor k to 0 \n run optimizer to determine poller matching \n resonance shall be at 13.56MHz, impedance should be minimized real part + 0j part; Antenna real impedance at 13.56MHz will influence this greatly \n Copy CS_Reader.opt and CP_Reader.opt to Poller matching \n  \n third step: \n Set the coupling factor to the measured value and the load as defined by the charging requirements. \n deactivate optimizer \n run simulation \n start tuning tool \n Tune the Listener to 13.56 MHz either with the series capacitance or series parallel combination. \n For applications with a low charge current and medium to low coupling a parallel matching may be more suitable. \n For this case it may be necessary to tune the Listener antenna to a higher frequency to prevent detuning of the Poller. \n Detuning at can be observed when the driver’s load impedance moves away from the real axis at 13.56MHz in the Smith Chart. \n Typical values for L_EMI and C_EMI are L_EMI = 120nH and C_EMI =470pF. R_EMI needs to be adjusted to the specific component that will be used. \n In general it is recommended to include the EMI filter on the listener device. For low power applications tests can be performed to see if it is really necessary to pass EMI. \n  \n fourth step: \n The impedance the driver sees at 13.56MHz (S11) shall be close to real axis 5 Ohms, the Listener might need to be retuned slightly to get the impedance the driver sees S11 back to the real axis. \n If the chosen matching topology will not allow a tuning close this impedance it might be considered to change the matching topology on the listener. \n  \n Verify performance in the system.
