1. A printed circuit board mounted radar system for monitoring a target region comprising:
an array of transmitting antennas mounted to a printed circuit board;
an array of receiving antennas mounted to the printed circuit board;
a wave deflection mechanism mounted to the printed circuit board configured such that:
waves which are transmitted by the array of transmitting antennas in a direction substantially perpendicular to the board are deflected by the wave deflection mechanism such that they are directed radially-away from the board in a direction substantially parallel to the board, and
waves reflected from objects within the target region radially towards the board from directions substantially parallel to the board are deflected by the wave deflection mechanism such that they are directed towards the receiving antennas in a direction substantially perpendicular to the board.
