RF WAVE BENDER
First Claim
1. A passive reflector system for redirecting a telecommunications signal, the passive reflector system comprising a plurality of passive reflectors, a first passive reflector being configured to receive an initial incident signal representing a message, and to reflect the initial incident signal as an initial reflected signal representing the message, the plurality of passive reflectors being arranged in sequence, each successive passive reflector configured to receive a respective incident signal representing the message, and to reflect the respective incident signal to produce a respective reflected signal representing the message, the passive reflectors being arranged so that the respective incident signal of each successive reflector is the respective reflected signal of the reflector preceding the successive reflector, each reflector being shaped so that when the initial incident signal comprises substantially planar waves, the respective reflected signals comprise substantially planar waves.

Abstract
The present invention relates generally to the field of wireless communication and, in particular, to the field of reducing shadowing and multipath fading over a wireless link. According to a broad aspect of this invention, there is provided a novel design of a passive reflector repeater and a set of methods to be used to configure a set of reflector repeaters to bend RF waves around obstacles along the direct path of a wireless link.

19. A method of locating a transmitting antenna in a system having at least one active receiver of known location and a number of reflectors also of known locations;
- the method comprising the active receiver estimating the location of the transmitter by estimating the AOAs or TOAs of the signal transmitted directly by the transmitting antenna to the active receiver and indirectly via the reflectors.
