Closed: Re: Directivity of antenna less than 1

There must be some issue in design setup ( like absorbing boundary conditions) otherwise directivity is always greater than or equal to 1 (0 dB), antenna gain can be less than 1 (0 dB).

Antenna simulation with defined port gives almost same result as port defined at the coaxial input. But defenelty port defined at coaxial input will be more close to real world design.
