From the NXP app notes:
AN1523 has a reference design for a mid-range less than one meter read distance antenna. The antenna is 34 mm x 15 mm.

AN0972 has a reference design for a "general purpose" antenna with an optimal read range of 2.5 meters. The antenna is 1.25" x 0.875"

AN0969 has a 98 mm long antenna design, with a read range of 1 m to 6 m depending on the substrate you use. Teflon and polystyrene are best; Rogers TMM6 is the worst but has the least variation across the frequency range.

AN1615 has a short range ring antenna design. 8.3mm diameter ring. Read range of 2 cm.

AN1685 has an 80mm x 35mm antenna design, with a 6 meter read range.
