Electrically small or compact antennas are limited by the physical fundamental laws. Introducing elements assets within an antenna structure can be an opportunity to overcome these limitations. Non-Foster elements are generally used to improve impedance matching of miniature antennas. In this paper, the Non-Foster elements are proposed as an innovative method to build up highly directive array antenna. This paper presents a design methodology for super-directive antenna arrays, centred at 868 MHz using two dipoles associated with Non-Foster elements.
