Such a phrase also at times consists of other modifiers describing the object of the prepositional phrase.

This does not have any connection to whether it is a phrase or a sentence. The length of the phrase may differ from two words to many more words. It does not contain the subject and the predicate both, so it is not a clause either. By itself, a phrase is not a complete sentence, as it does not relay a complete thought. A phrase is a group or combination of two or more words.
