Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parabolic antennas require costly waveguides to direct electromagnetic radiation, increasing manufacturing costs and complexity.
Innovation Solution
A parabolic antenna design featuring commercially available radiating elements placed at the focal point of a parabolic dish, eliminating the need for waveguides or directors by using a housing to enclose the dish and radiating elements, which can operate under different frequencies and switch between them for improved signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waveguides are used to guide electromagnetic radiation, then directional radiation is achieved, but manufacturing cost increases
Solution Approach 1:
The patent removes the waveguide component from the antenna system entirely. Instead of using a waveguide to guide electromagnetic radiation from the radiating element to the parabolic dish, the design places the radiating element directly at the focal point of the parabolic dish, allowing electromagnetic waves to be reflected and directed by the dish's geometry alone. This extraction of the waveguide eliminates the associated manufacturing costs while maintaining directional radiation capability through the parabolic reflector's inherent focusing properties.
Solution Approach 2:
The patent replaces the expensive waveguide with a simpler, more cost-effective configuration using commercially available radiating elements and a standard parabolic dish. The design accepts that individual components may have limited lifespans but compensates through the overall system's cost-effectiveness and ease of replacement, rather than relying on durable but expensive waveguide structures.
2Reliability
If waveguides are used to guide electromagnetic radiation, then directional radiation is achieved, but device complexity increases
Solution Approach 1:
The patent extracts and removes the waveguide component from the antenna system, significantly simplifying the overall structure. By placing the radiating element directly at the focal point of the parabolic dish and relying on the dish's geometric properties to direct the electromagnetic radiation, the design eliminates the need for complex waveguide structures, connectors, and alignment mechanisms, thereby reducing device complexity while maintaining directional radiation capability.
Solution Approach 2:
Instead of using a waveguide to actively guide and channel electromagnetic radiation through a structured path, the patent inverts the approach by using the parabolic dish's passive geometric reflection properties to direct the radiation. The radiating element emits waves that are naturally focused and directed by the dish's shape, eliminating the need for active guidance structures and reducing overall system complexity.

AI summary
The parabolic antenna includes a first radiating element, a second radiating element and a parabolic dish. The operating frequency of the first radiating element is different from the operating frequency of the second radiating element. The first radiating element and the second radiating element are disposed in front of the parabolic dish. Under different circumstances, the first radiating element and the second radiating element may operate simultaneously or non-simultaneously.
