Low-cost and compact antennas for wide-angle beam scanning in the mm-Wave band play a key role in the development of the next generation of terrestrial and satellite communication systems. Phased array antennas are currently getting a lot of attention for their excellent scanning with a low profile and mature manufacturing process [1]. However, the power consumption and losses due to their complex feeding network and large count of active components are still their main drawbacks. Both issues are overcome using spatially fed antennas (SFA) such as reconfigurable reflectarray (RA) or transmitarray (TA) antennas. These solutions avoid the feeding network, and the beam scanning is obtained using power-efficient controlling elements (PIN, MEMs, Liquid Crystal, etc.) [2]. However, they are still more costly and complex than solutions based on passive periodic structures combined with mechanical scanning (mainly reflector-based antennas, RA, or TA).
