Abstract
Transmission-line cloak provides a simple yet wideband solution for cloaking an object. In this letter, it is shown how the basic transmission-line cloak geometry can be modified so that the cloak structure itself acts as an antenna at a frequency well below the cloaking frequency. The structure retains its cloaking properties despite these modifications. Two types of cloak-antennas are presented: a dipole antenna and a monopole antenna. The operation of these antennas is verified using simulations and measurements. It is also shown how the antenna resonance frequency can be tuned by changing its geometry.
