Experimental demonstration of antenna blockage reduction with a transmission-line cloak

Transmission-line cloaking is a simple yet wideband technique for cloaking a mesh-like object. A novel transmission-line cloak design operating at microwave frequencies is presented with special emphasis in the design placed on ease of manufacture and practicality. The operation of the cloak is verified by studying the antenna blockage caused by the cloaked and uncloaked objects. It is shown both numerically and experimentally that the designed transmission-line cloak is capable of hiding a mesh-like metal object placed inside it from the incident wave in a variety of different scenarios and within a fairly wide frequency bandwidth. Also, the agreement between simulations and measurements is shown to be very good.
