The authors regret that the above article was published with errors in Fig. 4(a) (p. 3) and Fig. 7 (p. 5), reprinted correctly below:

Figure 4. (a) Radiation efficiency, total efficiency, and (b) realized gain of the proposed planar wideband antenna.

Figure 7. Reflection coefficient of the proposed metasurface.

The change in Fig. 7 should be accompanied by a change in the body text on pp. 4–5, as well as the change in figure caption above. The sentence was originally published as “The simulated S-parameters of the proposed metasurface are depicted in Fig. 7.” This should have been “The simulated reflection coefficient of the proposed metasurface in terms of co-polarized and cross-polarized components is shown in Fig. 7.”
