Abstract

This paper presents metamaterial-inspired solution to mitigate scan blindness in phased arrays at RADAR frequency taking advantage of less mutual coupling and compactness of metamaterial arrays. This is done by redesigning a metamaterial antenna at RADAR frequency, feeding it with shielded coaxial probe to reduce side lobe level thus making it practical for planar arrays implementation. Input reflection coefficients and mutual coupling is presented varying phase difference among antenna feeds. Results from HFSS confirmed that there is no scan blindness in these newly designed phased metamaterial arrays.
