I'm working on RFID project . and I want to design the reader antenna at 13.56MHz to transmit and read at maximum range 1.5 m to passive tags .

if someone can provide me with proper equations to calculate inductance of the coil to be 0.225μH .:)

A single layer coil, length,l, & radius,r, N, no of turns,. can be calculated: L=[ rN ]squared /9r +10l. If r=.75, l=.1, N=2, then L about .29 uH. Spreading turns will reduce L. Allied Radio 1960
