How to test EMC Antenna - Dual Polarized Horn Antennas ( Quad ridged horn antenna & Open boundary quad ridged horn antenna? The Dual Polarized Horn Antenna includes HQ model - Quad-ridged Horn Antenna, Open Boundary Quad-Ridged Horn Antenna -HR Model. These Horn antennas have an electronic switch that may simultaneously test horizontal and vertical or +-45deg polarization, as well as a couple that can test circular polarization. The dual-polarized antennas are mounted on a special table or wall. FT-RF also supply the calibration service for these antennas in case the customer wants to use them for a certain purpose. How to test EMC Antenna - Single-polarized Horn Antennas (Double ridged horn antenna & Open boundary double ridged horn antenna)? HA Model - Double-Ridged Horn Antenna & HB model - Open Boundary Double-Ridged Horn Antenna are commonly used to replace the antenna method's calibration antenna. When HA calibration is utilized, the calibration site is lost (patch loss uses a network analyzer) Enter the antenna's gain (minus the gain of the antenna, equal to the address of the object under test, return to zero) There is only one technique to compute antenna gain. The path loss patch loss subtracts the antenna's gain and substitutes the antenna under test to obtain the antenna's gain. Rotate the object under test...
