Please who can draw to me or give me the footprint of the coil **broken link removed** i have a doubt in understanding the dimension of the coil
 

The footprint diagram is on page 3 of the datasheet. What doubts do you have?

Keith.
 

they said that the dimension of the coil is 10.4x10.4 but in the layout recommendation they put 3.6x11 :(
 

You should consider the possibilty, that the room occupied by a component (the so-called courtyard) is larger than the rectangle enclosing the pads. In my opion, the datasheet is soooo obvious...
 

Correct. 10.4mm x 10.4mm is the dimension of the coil. The two pads shown at 11 x 3.6 are where you put the pads for the part to solder to. Normally you would create a footprint with the pads as shown in the drawing and then add a no-go area and silk screen to show the overall outline of the part.

Here is what it might look like

You can see the pads. The rectangular area is a "keepout" area. This inductor is slightly different to yours - it is a shielded rectangle rather than open.
