If your husband was deported, generally the rule is he cannot come back in for 5 years, counting from when he exited. There are exceptions such as if he was removed as an aggravated felon which would be longer. He may be eligible to come
The bigger concern is that if he was in the US illegally for 1 year or more, he triggered the 10 year bar upon his exit. There is a waiver available but I would suggest talking to an immigration attorney about this.
