The loops have a gap at the top. BTW, I am not using an anechoic chamber. They are placed in a large open area with at least 3 meters of empty space behind each of them. The current applied to the transmit loop is being monitored with a current probe.

Sounds like you need to be a metrologist, or a calibration technician. Some of us do programming but it is not an official part of the job training. You do however need to know math, advanced electronics, and how to use computers.

What am I doing? Well, I am trying to validate loop antenna calibrations using a transmit loop antenna with a 0.28 radius to test the antenna factor of receive loop antennas of various radii. It works fine when they are similar in size but I'm having difficulty if the receive loop is...

The loops are 1 meter apart. The testing frequency range is from 1kHz to 30MHz. Both of the antenna are 1-turn loops. I am using the setup described in IEEE-291-1991. It worked fine when my receiving antenna had the same radius as my transmit loop, but now that I am testing a smaller...

I am transmitting an electromagnetic field from a loop antenna of 0.28 radius to one with 0.216 radius. I know the antenna factor of the receiving antenna but when I add it to the measured field strength, it does not equal my calculated transmit field strength. Should the shorter antenna be...

Contact separation, between the male and female center pins, is a contributing factor to the mismatch between a source and load. For a good visualization go to www.phy.davidson.edu/instrumentation/neets.htm and check out the modules on wave propagation, and microwave principles.
