Antenna gain calculation For 2-d Horn antenna

Please login with a confirmed email address before reporting spam

Hi

I recently wanted to caluculate the antenna gain for a typical Hoen antenna in 2-D. I have read the following thread.

https://www.comsol.com/forum/thread/20515/calculating-antenna-gain?last=2011-10-24T13:31:51Z

However as I found out, Comsol has a specific parameter emw.gaindBEfar for gain calculation when farfield analysis in included.

I simulated a typical horn and I am quite sure the value Comsol derived is wrong. Comsol Gives 15dbi where values near 25 or more are expected based on this article 10.1109/TAP.2012.2207051 on Fig 6.

I attached the mph files. Please chek if I did anything wrong.
