Abstract: A compact planar sub-wavelength array is proposed, which has planar antenna elements etched with defect oval rings on the surface. The array demonstrates a property of 1/20 wavelength super-resolution combined with time-reversed electromagnetic waves. This design is simple in structure, easy to integrate and convenient for the printing design of circuit boards. [ABSTRACT FROM AUTHOR]
