L96-M33 chip antenna type

We are using thousands L96-M33 many years with very good results and we continue to use it. Now I’m creating other version with BG951A-GL module.
And I would like to use the same chip antenna that used on L96-M33. Looks to me that it’ best to start to use.
Can some body to get me exact info about what chip-antenna is used in ?
