Antenna Farfield Measurement
January 14, 2020 - 8:04am

I am trying to get the value of the h field with a horn antenna as a reference antenna. I used a 90 degrees waveguide twist with the horn antenna in preset to measure le level of the received signal. But I am getting strange values. 

Am I proceeding the right way to measure the h field? If yes is it a scaling issue if the values that I’ve got? If not how can I measure the h field knowing that I only have a stage ratatiné in the E filed? 

Thanks!

Please provide the spec

What is the antenna spec and what is the output you are getting?

Antenna measurement techniques refers to the testing of antennas to ensure that the antenna meets specifications or simply to characterize it. ... The first technique developed was the far-field range, where the antenna under test is placed in the far-field of a range antenna. Exactly are we looking for when we test or measure antennas? ... The final antenna measurement section illustrates the new field of SAR measurements and ... The source antenna must be placed in the far field of the test antenna.
