Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external beam shaping lenses are used with bicone antennas, then elevation patterns can be shaped, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the beam shaping lens and the bicone antenna into a single integrated structure. The lens is formed as an integral part of the antenna body from the same dielectric material, eliminating the need for separate external lens components. This merging resolves the technical contradiction by maintaining elevation pattern shaping capability while significantly reducing manufacturing complexity and the number of assembly steps.
Solution Approach 2:
The integrated structure serves multiple functions simultaneously: the dielectric body provides mechanical support, the conical elements function as antenna radiators, and the integrated lens shapes the beam elevation pattern. This multi-functionality eliminates the need for separate dedicated lens components, reducing manufacturing complexity while preserving adaptability for different elevation patterns.
2Adaptability or versatility
If external beam shaping lenses are used with bicone antennas, then elevation patterns can be shaped, but manufacturing cost increases
Solution Approach 1:
The lens and antenna are manufactured as a single integrated component from the same dielectric material using the same molding process. This eliminates the need for separate lens manufacturing, material procurement, and assembly operations, thereby reducing overall manufacturing cost while maintaining elevation pattern shaping capability.
Solution Approach 2:
The single dielectric body performs multiple functions: structural support, antenna radiation (through conical elements), and beam shaping (through integrated lens). This multi-functionality consolidates manufacturing operations into a single process, reducing total manufacturing cost compared to producing and assembling separate components.
3Adaptability or versatility
If external beam shaping lenses are used with bicone antennas, then elevation patterns can be shaped, but mechanical robustness is reduced
Solution Approach 1:
The lens and antenna form a single monolithic structure without joints, interfaces, or fasteners that could fail. This integration eliminates mechanical weak points and ensures the lens remains precisely positioned relative to the antenna elements, thereby enhancing mechanical robustness while maintaining elevation pattern shaping capability.
Solution Approach 2:
The single dielectric body provides both structural support and beam shaping functions, eliminating the need for separate lens mounting structures and fastening mechanisms. This reduces the number of potential failure points and improves overall mechanical reliability.
4Adaptability or versatility
If external beam shaping lenses are used with bicone antennas, then specific elevation shaping requirements can be met, but additional handling and complications are required
Solution Approach 1:
The lens and antenna are manufactured as a single integrated component, eliminating the need for separate handling, positioning, and assembly operations. This resolves the technical contradiction by maintaining elevation pattern customization capability while significantly simplifying installation and reducing handling complexity.

AI summary
A broadband omni-directional bicone antenna. The antenna can comprise conductive surfaces of conical voids provided within a solid dielectric structure. The outside surface of the solid structure can support a radio frequency (RF) lens geometry operable for beam forming. The beam forming can modify the elevation pattern of the electromagnetic radiation from the bicone antenna. The solid dielectric structure may be machined or molded from a single piece of material. The conical voids provided within the solid structure can be metallized to provide conductive bicone radiators. The outer surface beam shaping lenses can be zoned or continuous and can provide elevation patterns with increased gain, cosecant squared falloff, or various other patterns. The beam shaping lens may be formed from any low-loss dielectric. Alternatively, the lens may be formed from a less dense material such as dielectric foam that can support radial conductive beam forming vanes.
