Solution Overview
Problem
Existing double-conical antennas face challenges in achieving a stable, symmetrical, and interference-free structure for precise electromagnetic field emission, with issues in mechanical and electrical stability, especially near the apex, and complex handling.
Innovation Solution
A two-part, axisymmetric double-conical antenna design with a connecting part shaped like a cone, featuring rotational symmetry, mechanical and electrical connection elements, and a cylindrical or hyperboloid shape at the apex for increased stability, along with a comb generator and insulating materials to prevent field distortions and simplify signal routing.

Engineering Contradiction Analysis
1Reliability
If a double-conical antenna is constructed with two hollow cone parts connected at the apex, then the antenna can emit electromagnetic waves, but the structure becomes mechanically unstable and prone to field distortions in the apex region
Solution Approach 1:
The antenna is divided into two separate hollow cone parts that are connected through a transition piece rather than directly joined at the apex. This segmentation allows each cone to maintain its structural integrity while the transition piece provides mechanical support, eliminating the instability associated with direct apex connection.
Solution Approach 2:
A transition piece serves as an intermediary element between the two hollow cone parts. This intermediate structure provides mechanical support and stability to the apex region while maintaining the electrical continuity needed for electromagnetic wave emission, thus resolving the mechanical instability without compromising the antenna's functional integrity.
2Device complexity
If the two hollow cones are directly connected at the apex, then the antenna structure is simplified, but field distortions occur and symmetry is compromised
Solution Approach 1:
By introducing a separate transition piece as a distinct component, the antenna maintains a simple overall structure while achieving precise geometric symmetry. The transition piece can be independently manufactured to exact specifications, ensuring the apex region maintains rotational symmetry without complicating the cone structures themselves.
Solution Approach 2:
The transition piece provides localized structural enhancement at the apex region where precision is critical, while the rest of the antenna maintains its simple conical geometry. This allows high manufacturing precision to be applied only where needed (at the connection point) without increasing the complexity of the entire antenna structure.
3Reliability
If mechanical connection elements are added to connect the antenna parts, then structural stability improves, but the routing of signal cables becomes complex
Solution Approach 1:
The transition piece serves multiple functions simultaneously: it provides mechanical support for structural stability, maintains electrical continuity for signal transmission, and offers a integrated pathway for cable routing. By combining these functions in a single component, the design achieves mechanical stability without increasing cable routing complexity.
Solution Approach 2:
The mechanical connection, electrical connection, and cable routing functions are merged into the transition piece. This integration eliminates the need for separate components for each function, thereby achieving mechanical stability while keeping the overall structure and cable routing simple.
4Ease of manufacture
If the antenna is constructed as a single integrated piece, then manufacturing is simpler, but the ability to assemble and disassemble for handling and transport is reduced
Solution Approach 1:
The antenna is segmented into modular components (two hollow cones and a transition piece) that can be manufactured separately using simple processes, then easily assembled through the transition piece. This segmentation maintains manufacturing simplicity while enabling easy assembly and disassembly for handling and transport.
Solution Approach 2:
The antenna design allows dynamic reconfiguration between assembled and disassembled states. The mechanical connection through the transition piece enables easy assembly and disassembly, making the antenna adaptable for different operational requirements such as transport, storage, and rapid deployment, without compromising manufacturing simplicity.

AI summary
The double conical and axially symmetrical antenna has two hollow cones isolated against each other. The body of the antenna has antenna pieces (6). The former antenna piece has the former hollow cone and a section of the latter hollow cone that is adjacent to the former hollow cone and serves as connecting part. The latter antenna piece has a truncated conical part of the latter hollow cone. The connecting part and the latter antenna piece are connected with each other in detachable manner, particularly in screwable manner. An independent claim is included for a transmitting antenna with an antenna piece.
