“…The largest directivity always appears at b/a about two, the ratio of the outer and inner radius the LHM shell. This result has been explained by the focus effect of the LHM shell [6]. The contour maps indicate the good directive emission requires optimizations for the size of LHM shell.…”

“…Recently, it is proposed that metamaterials can be used to develop lower reflectivity antennas or sensors. For example, Alu et al [5] proposed the cloaked sensor that uses metamaterials to cloak a sensor without affecting its capability to receive; Wu et al [6] theoretically proved the antenna involving LHM (LHM antenna) could be a directional antenna with lower RCS. These kinds of sensors or antennas may have important applications such as stealth antenna.…”

Metamaterial antenna involving a shell of left-handed materials (LHM) and a line source could be a directional antenna with lower RCS. To optimize the performance of the antenna, we studied the effects of the line source position and the properties of LHM shell on the directional radiation. The results show that these factors can greatly change the directional emission of the antenna. To maximize directive emission, one needs to optimize the source position and the size of LHM shell, and to balance the directivity and side-lobe peak levels of the antenna.
