Jennifer Day, 34, who made the false allegation against former boyfriend Andrew Saxby after a row, was told by the judge that she had undermined efforts to treat genuine rape victims fairly and sympathetically.
The court also heard that Mr Saxby was subjected to 'degrading and upsetting' examinations while being held by police for ten hours.
Judge Ian Graham said the investigation had wasted £4,000 of taxpayers' money and 270 police man hours.
He added: 'The police have put great stores on providing sympathetic treatments of women who make genuine complaints of rape and you abused that.
