Text Correction
There was an error in the original paper [1].
After Equation (3) on page 8, instead of “According to the function (1), the beam is upward tilted”, it should read: “According to the function (3), the beam is upward tilted”.
A correction has been made to Section 2.3. Stable Radiation Patterns and Titled Beams, seventh paragraph:
According to the function (3), the beam is upward tilted, and the calculated angle is −50°, given in Figure 12. Actually, the tilted angle of the proposed antenna with hg = 8 mm is −40°, presented in Figures 10 and 11. The difference between the angles is mainly due to the assumption of the infinite ground in the function.
The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
