What is the unit of Diversity Gain in MIMO antenna?

I received a response to add the unit of diversity gain in plot. When we go from formula of DG which is computed from ECC, it is unitless, because ECC is unitless and also we do not use any...

What is the unit of CCL in MIMO antenna?

I found various units at various literatures for CCL. In some figures I found it is placed as CCL (dB). But somewhere else the formula provided is - log(base 2)det(Br), here base is 2, also in...

How can we diffentiate among 4 various gains of MIMO i.e. IEEE Gain, Realized Gain, Mean Effective Gain and Diversity Gain?

The simulation tools provides us two diffferent types of gains for patch antenna those are Gain IEEE and Realized Gain. What is the difference or calculation between them. Further if go for...

Why MEG is always below-3dB?

In Literatures I found that Mean Effective gain is always found to below -3 db, at this point also efficiency is 100%. can enyone explain this mor better. Also if human head is around it may...

Why the diversity gain for a mimo antenna goes close to 10?

I seen many papers and performend experiments. The diversity gain approaches to 10 on a general basis. why it is so. as per formula it is OK, but is there any theoritical justification. can...

For a multiport antenna I have farfield data in form of H-co, H-Cross, E-CO and E-cross, for some frequencies, How can I calculate the ECC?

I need to calculate ECC from farfield data. I have data of radiation patterns for H-Co, H-Cross, E-Co and E-Cross at some frequencies. Can anyone tell the method to calculate ECC using farfield...
