1. A radio frequency (RF) detector array for use with a magnetic resonance imaging (MRI) system, comprising: a plurality of conductive array elements being substantially parallel to a conductive ground plane; a plurality of capacitors, wherein at least one capacitor is shunted from each array element to the ground plane to adjust a corresponding electrical length of each conductive array element; and, wherein a combination of each respective array element, at least one corresponding capacitor and the ground plane forms a resonator that resonates at a selected frequency.
