We are using the BQ51013 and BQ500210 evalaution boards as a reference design, but we only need 0.75A, not the 1A which the kits are rated for. Can we get away with a smaller loop antenna? If so how much smaller?

Smaller coils can be used, we are evaluating a 26mm diameter pcb coil for a 200mA application. But a shield is required behind the coil. I will contact you and we can work off line on this application.
