The possibility of microwave near-field focusing using a simple width-tapered microstrip leaky-wave antenna is theoretically and experimentally proven in this paper. The design procedure to obtain the modulation of the microstrip width along the antenna length is described, illustrating the conditions and limitations for optimum focusing at a certain focal point and using a given substrate. A 7.5 λ0 -long microstrip lens is designed to operate at 15 GHz, and its focusing properties are studied… CONTINUE READING
