An MRI antenna array including a housing and a substrate, antenna elements and circuitry encapsulated by the housing. The housing, antenna elements, and substrate are flexible to allow the housing to distort in three dimensions to closely conform to contours of a patient. The antenna elements are mounted to the substrate in a manner that permits each element to maintain a desired resonance when the housing is distorted in three dimensions. The circuitry is electrically coupled with the antenna elements to maintain tuning and isolation of the elements when the housing is distorted in three dimensions. The housing, antenna elements, and substrate may be elastic to allow the housing to be worn by a plurality of different sized patients so that the housing is in close contact with the patient and conforms to contours of the patient.
