Solution Overview
Problem
Conventional multiband patch antennas are cumbersome and expensive to manufacture due to their stacked design, which complicates the production of compact, cost-effective antennas that can provide durable and efficient dual-band or RTK L-band operations.
Innovation Solution
A multiband patch antenna design featuring a substrate layer with a base element and a multi-resonance patch element on its surface, incorporating a pattern of outward extending resonance formations and proximity feed elements connected to a multiband hybrid coupler circuit, allowing for capacitive feeding and simultaneous reception of multiple bands without covering the entire substrate surface, utilizing additive manufacturing and pre-metallized high electric paste for efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stacked patch antenna design is used for multiband operation, then dual-band coverage is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges multiple band operations into a single planar patch antenna structure rather than using stacked designs. The patch element incorporates multiple resonance formations that enable dual-band coverage while maintaining a simple single-layer construction, thereby reducing manufacturing complexity and cost.
Solution Approach 2:
The patch antenna element is designed to perform multiple functions simultaneously - supporting both L1 and L5 bands within a single structure. The resonance formations are configured to create multiple resonant frequencies, allowing one antenna to replace what would traditionally require multiple stacked elements.
2Adaptability or versatility
If conventional stacked patch antenna design is used, then multiband operation is achieved, but manufacturing cost increases
Solution Approach 1:
The invention combines multiple band capabilities into a single planar structure that can be manufactured using standard PCB techniques. This eliminates the need for complex stacked assemblies and reduces manufacturing steps, thereby lowering production costs while maintaining multiband functionality.
Solution Approach 2:
The patent uses parameter optimization in the resonance formation geometry to achieve dual-band operation. By carefully designing the shape, size, and configuration of the resonance formations, the antenna achieves L1 and L5 band coverage through a single structure that is straightforward to manufacture using conventional methods.
3Volume of moving object
If compact patch antenna design is implemented, then size is reduced, but manufacturing durability may be compromised
Solution Approach 1:
The patent applies local quality optimization by strategically positioning resonance formations in specific areas of the patch element. This localized design approach maintains structural integrity in critical areas while achieving compact overall dimensions, ensuring manufacturing durability is not compromised by size reduction.
