What's new in antennas?

Innovative designs, novelty, and creative ideas, currently reported in the international antenna literature, are highlighted in the areas of elements, traveling-wave arrays, apertures, arrays, measurements, and material development. Manufacturing and operational aspects are noted and the driving forces identified. The extent to which antenna technology is mature, the role of research, and degrees of design freedom are considered in some depth. Influences and innovation likely to be experienced within the next five years are conjectured upon, together with some speculation for the more distant future.<
