Hi Bryan,
I wasn't proposing a whip antenna but yes a chip antenna is what I meant for you guys. Also, yes you need a network analyzer to work with 2.4 GHz wireless devices otherwise you're in the dark as you mentioned.
If you want to quickly learn how to do this work (design an antenna, design antenna matching networks, "drive" a network analyzer, etc) then I could help you. I've mentored many engineers over my career.
