Abstract

In this paper, a Lens-Dielectric Resonator combination is proposed to improve RCS of dielectric resonator tags to be used in a self-localization system where high RCS is essential to combat clutter signals. As a proof of concept, a cylindrical dielectric resonator is located in the focal area of a 200 mm diameter (3.5 λ at 5.2 GHz) 2D Luneburg Lens sandwiched between two tapered metal plates. Two approaches of realizing the continuous variation of the Luneburg lens dielectric permittivity are implemented, fabricated, and tested: by using stepped cylindrical layers of dielectric material (fabricated by machining process) and by using effective medium theory in which the lens is constructed from a group of cells made of various cuboids sizes connected to trapezoidal rods (fabricated by 3D printing technology using PP). A good compatibility between DR and lens is observed. The improvement in RCS is found to vary depending on DR resonance mode. For the HE₁₁ mode, a 20 dB improvement is achieved.
