In this video, I have shown practically how to measure mutual coupling between two antenna elements of a 2x2 MIMO antenna by using a vector network analyzer (VNA). I am using Agilent E8364B VNA. But you can use your own VNA. It does not matter. The principle of measurement remains same. Mutual coupling is undesirable for practical MIMO antenna design. In practice, any value below -20 dB of mutual coupling is considered good.
---------------------------------------------------------------------------------------------
Before starting the measurement you should calibrate your VNA. Watch how to calibrate a VNA by using SOLT method:
Agilent E8364B Calibration: • Two Port Calibration of Agilent E8364...

Agilent E5071B Calibration: • Two Port Calibration of VNA (Agilent ...

Please can you make a video about suspended stacked patch antenna with showing how to feed them? I am really following all of your videos but I couldnt one any video about this one .I am really wondering this one please take a video for this one.Thank youu

Mr Nazmul Hassan please can you help me with how to extract equivalent circuit of MIMO antenna from CST to ADS and them compare the results?

Hi! I am doing my thesis, I am measuring the mutual coupling in an array of 1x16 antennas. I am a question, The 16 antennas must have the same value of s11?

those monopoles are a variation of your original DGS monopole antenna loaded with U-shape stub?

Sir how can we find the antenna is dual polarized in CST

Nice video bro......I am sorry but I think it is 1x1 MIMO instead of 2x2?
