Depends on how you want to fly. If you want to fly all around you then a cloverleaf on the transmitter and a skewplanar wheel on the receiver is the best option.
If you want to fly long range but in a general direction, then a cloverleaf on the transmitter and a helix (helical) antenna on the receiver pointed in the direction you want to fly is the best option.
An antenna can be circular (helical, cloverleaf) or linear (rubber duck antenna, standard patch antenna) polarized. For 5.8 GHz, linear polarization is pretty much useless. Circular polarization (skewplanar wheel, cloverleaf, helical) is best for 5.8 GHz.
