To tailor the conical beam by using planar superstrate

Here, the planar superstrate is used to tailor the conical beam. In the applications of conical beam antenna, making a good balance between the wider coverage and the higher gain is always a challenge, while the planar superstrate provides the freedom of design. Through adjusting the parameters of the planar superstrate, it is possible to change the coverage range and to make the beam more flat. To verify the proposed method, some simulated results are presented and two prototypes with homogeneous dielectric slab superstrate and with patterned dielectric slab superstrate are fabricated and measured. The simulated results and the measured ones are in good agreement.

Automated summary

The planar superstrate is used to tailor the conical beam for wider coverage and higher gain in conical beam antenna applications, providing design flexibility. By adjusting the parameters of the planar superstrate, the coverage range can be changed and the beam can be made more flat. Simulated and measured results validate the effectiveness of this method.
