G/T estimation for DVB-SH automotive 2-port switchable CP antennas

In this contribute a multi-port approach for the estimation of the G/T parameter for DVB-SH RX antenna prototypes is presented. G/T evaluation is done from the measurements of the active gain pattern and amplification chain parameters. The proposed methodology has been compared with the Y-method. A link between the two has been presented and a discussion about advantages and disadvantages is given.
