Abstract (en)
[origin: WO2015023801A1] An antenna assembly includes a first active antenna element and a second active antenna element, each of which may be a dipole. A first set of independently-switchable radio-frequency reflectors are positioned around at least the first active antenna element. These first switchable radio-frequency reflectors may also be positioned around the second active antenna element. Alternatively, a second set of independently-switchable radio-frequency reflectors may be positioned around the second active antenna element. The switchable reflectors enable controlled perturbation of the communication channel between the antenna assembly and a remote communications node, enabling securely encrypted communications.
