A notched dielectric resonator antenna unit-cell for 60GHz passive repeater with endfire radiation

This paper presents the preliminary design of a 60GHz passive repeater endfire array with dielectric resonator antenna (DRA) elements. The proposed DRA element utilizes simple notches at opposite corners of a square DRA to obtain polarization-conversion. By combining two DRA with notches on opposite diagonals, endfire radiation can be obtained. A 6×1 linear array is optimized and simulated as an initial demonstration.
