By "card", I presume you mean PCMCIA or PC Card type of wi-fi device.

Hormel? Didn't they invent spam? Are you sure you want to be known
as a spammer? Maybe if you wear one of these:

nobody will notice.

I'll presume that you have no idea which Hawking product you own and
therefore will have limited success with your adventure into Learn by
Destroying. However, I can offer some general guidelines.
If you look at serial number label on the device, you'll probably see
an FCC ID number. Plug the number into the FCC ID search at:
<https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/GenericSearch.cfm>
and look at the inside photos. That will give you an idea of whether
a coax cable pigtail can be attached. The general proceedure is to
tear your device apart, remove or disconnect any internal antenna, and
attach a coaxial cable pigtail. The soldering is critical and has a
huge impact on performance. If you've never soldered before, this is
not a good beginners exercise.
See:
<http://repair4laptop.org/wireless_lan_antennae.html>
for a few clues.
My guess is that the typical Hormel Spam can is too small to be useful
as a 2.4GHz antenna. I'm not sure what you're thinking in the way of
how the antenna is to be used (vehicle, bicycle, coffee shop, fixed
location, etc) so there's no way to recommend a specific type of size.
If you plan to build your own, I recommend one of the biquad types:

A good question is how much gain do you need. I have no idea because
you didn't supply any clues as to how it's to be used. As a rule of
thumb, if you *ADD* 6dB of antenna gain (minus coax cable losses), you
will double your range. 12dB gain will give you 4 times the range.
As to the build or buy decision, that's yours to make. If you think
you can build any of the above, then I suggest you build something.
