Solution Overview
Problem
Existing wireless local area network antennas are bulky, costly to manufacture, and aesthetically unappealing due to external mechanical structures, limiting their integration into devices and compromising signal reception and transmission performance.
Innovation Solution
A multi-input multi-output antenna system featuring dual-feed and dual-band antennas arranged in a polygon configuration with a shorting element, allowing for compact size, reduced manufacturing costs, and improved aesthetic integration by eliminating the need for external sleeves, while maintaining effective radiation performance across multiple frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external antenna structure with plastic/rubber sleeves is used, then antenna can be fixed and operated, but manufacturing cost increases and manufacturing difficulty increases
Solution Approach 1:
The patent removes the external plastic/rubber sleeves and mechanical fixing structures from the antenna design. The antenna elements are directly integrated into the housing structure, eliminating the need for separate protective sleeves and complex assembly processes while maintaining structural stability.
Solution Approach 2:
The antenna structure is merged with the housing structure itself. The housing serves dual purposes as both protective enclosure and antenna support structure, integrating functions that were previously separated into distinct components.
2Ease of operation
If external antenna structure is used, then antenna can be installed and adjusted, but antenna cannot be built-in and aesthetic appearance deteriorates
Solution Approach 1:
The antenna elements are nested within the housing structure rather than protruding externally. The antenna components are concealed inside the device casing, creating a sleek external appearance while maintaining functional capabilities through strategic placement and design of the internal antenna elements.
3Ease of operation
If external antenna structure is used, then antenna can be positioned for signal reception, but antenna is exposed to external forces and easily damaged
Solution Approach 1:
The antenna structure is merged with the housing structure itself. The housing serves dual purposes as both protective enclosure and antenna support structure, integrating functions that were previously separated into distinct components.
Solution Approach 2:
The housing structure provides inherent protection to the antenna elements before any external damage can occur. The antenna elements are positioned within the protective enclosure, cushioning them against external forces and physical damage.
4Reliability
If external antenna structure is used, then antenna can transmit and receive signals, but antenna occupies much space and reduces product integration
Solution Approach 1:
The antenna design transitions from external three-dimensional protrusion to integrated planar or shallow-profile structure within the housing. This dimensional reconfiguration reduces the space occupied while maintaining signal transmission and reception capabilities through optimized element placement and geometry.
