The gain difference of 2.4GHz antenna

Hi,
The attachments are 5 types of 2.4GHz antenna collected form the internet. Can anyone tell me the gain difference between them and which one is the best suitable for portable mobile application?
Thanks.

The gain of all these antennas are pretty similar (about 2dBi in average), but this depends by the PCB material used. The meander Inverted-F type has wider bandwidth, when the Inverted-L has the narrowest.
