Summary:The invention discloses a fixed type quasi-optical Faraday rotator performance determination method, which belongs to the millimeter wave quasi-optical technology field. The method comprises the following steps: placing a polarized grid and a Faraday rotator sequentially between two polarized antennas wherein both the polarized directions of the transmitting antenna and the receiving antenna are vertical to the ground; through the adjustment of the inclined angles of the polarized grid wires and the ground, changing the inclined angles of the Faraday rotator entering linear polarization direction and the ground as well as the Faraday rotator entering wave polarization direction and the ground; when the Faraday rotator entering linear polarization direction and the Faraday rotator entering wave polarization direction differ in 90 degrees, measuring the two orthogonal components of the emitted elliptically polarized waves of the Faraday rotator without having to rotate the receiving antenna for 90 degrees so th
