Groove-Embedded Antenna Unit Reduces Transceiver Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless transceiver apparatuses occupy relatively large space due to the thickness and volume of their omnidirectional antenna units, which are typically three-dimensional structures requiring separate processing and assembly on metal carriers or shielding covers.
Innovation Solution
The antenna unit is disposed in a groove on the metal carrier, with a dielectric substrate bearing the radiation patch and feeding structure, reducing the overall thickness and volume of the transceiver apparatus, and allowing for non-centrosymmetric configurations that maintain high roundness and applicability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional omnidirectional antenna unit is disposed on a metal carrier or shielding cover, then the antenna provides large signal coverage area and homogeneous radiation, but the total thickness and volume of the wireless transceiver apparatus becomes relatively large
Solution Approach 1:
The patent merges the omnidirectional antenna unit with the metal carrier by directly forming the antenna elements on the metal carrier surface, eliminating the need for separate antenna structures. This integration reduces the total volume while maintaining the omnidirectional radiation pattern and signal coverage area through the combined structure.
Solution Approach 2:
The patent extracts the essential radiation elements from the conventional three-dimensional antenna structure and implements them as planar patterns directly on the metal carrier. This extraction of the core functional elements allows the antenna to maintain its omnidirectional coverage while significantly reducing the overall volume occupied by the transceiver apparatus.
2Reliability
If a conventional omnidirectional antenna unit is separately processed and assembled, then the antenna structure is independent and functional, but the total thickness of the wireless transceiver apparatus increases due to superposition of components
Solution Approach 1:
The patent combines the antenna unit with the metal carrier into a single integrated structure, eliminating the superposition of separate components. The antenna elements are formed directly on the metal carrier surface, which maintains reliable antenna functionality while reducing the total thickness by removing the need for separate antenna assemblies and their associated mounting structures.
Solution Approach 2:
The patent nests the antenna elements within the planar surface of the metal carrier, embedding the radiation structures into the existing component rather than adding them as external attachments. This nesting approach maintains antenna reliability while minimizing the increase in total thickness.
3Volume of stationary object
If the antenna unit is disposed in a groove on the metal carrier, then the space occupied by the transceiver apparatus is reduced, but the manufacturing complexity increases due to groove formation and component integration
Solution Approach 1:
The patent merges the antenna unit with the metal carrier by forming the antenna elements directly on the carrier surface, eliminating the need for separate groove formation and assembly steps. This integration reduces manufacturing complexity while maintaining the space-saving benefits of the compact design.
Solution Approach 2:
The patent segments the antenna elements into discrete planar patterns that can be independently formed on the metal carrier surface. This segmentation allows for simplified manufacturing processes such as screen printing or etching, reducing the overall manufacturing complexity compared to forming complex three-dimensional antenna structures in grooves.
