This article addresses the problem of measuring superdirective electrically small antennas mounted on printed circuit broads (PCBs). Different configurations for connecting the excitation system (SMA connector and coaxial cable) to an array of 31 × 25 mm 2 integrated in a PCB of 110 × 70 mm 2 are studied. This configurations are evaluated based on the cable effect on the array's input reflection coefficient and radiation pattern. Obtained results show that properly connecting the cable with the array mitigates its effect, and hence, it can be measured. © 2015 Wiley Periodicals, Inc.
