Abstract:This work describes a simple, low-cost electrically steerable antenna system suitable for long-distance point-to-point links based on WiFi technology. The antenna consists of a tunable mirror, assembled as an array of closely spaced passive dipoles (scatterers) illuminated by one driven element. The scatterers are arranged in multiple layers that contribute overlapping ranges of phase shift. While collectively providing full 360 degrees of phase range, this approach enables individual scatterers to provide gre… Show more
