Patterned Side Mirror for 5G Beamforming Antenna Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of a mirror around a beamforming antenna can block radio waves, deteriorating the scanning performance of the antenna due to its metallic properties, which is particularly problematic in high-frequency millimeter wave communication systems like 5G.
Innovation Solution
A beamforming antenna assembly with a patterned mirror that allows beams to pass through, using a plurality of cruciform patterns formed by rectangular shapes spaced at predetermined intervals on the mirror glass, ensuring the beamforming antenna's performance is maintained while minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mirror is placed around a beamforming antenna, then the antenna structure is compact and protective, but the metallic mirror blocks radio waves and deteriorates scanning performance
Solution Approach 1:
The mirror surface is segmented into multiple regions: a first region with a pattern that allows radio wave passage and a second region without the pattern that provides protective coverage. This segmentation enables different portions of the mirror to serve different functions simultaneously.
Solution Approach 2:
Different regions of the mirror have different properties: the first region has a patterned structure with specific transparency characteristics for radio waves, while the second region has a solid reflective surface. This local differentiation optimizes both antenna performance and protective function.
2Reliability
If a pattern is formed on the mirror to allow beam passage, then antenna performance is maintained, but the mirror's reflective functionality may be reduced
Solution Approach 1:
The mirror is divided into a first region with the pattern for beam passage and a second region without the pattern for maintaining reflectivity. This ensures that the patterned area is sufficient for antenna performance while the non-patterned area preserves the mirror's reflective function.
Solution Approach 2:
The mirror exhibits spatially varying properties: the first region has reduced reflectivity but increased radio wave transmission due to the pattern, while the second region maintains high reflectivity. This local quality differentiation resolves the trade-off between beam passage and reflection.
3Reliability
If additional antennas are added to compensate for blocking, then coverage is improved, but device complexity and cost increase
Solution Approach 1:
The mirror serves multiple functions: it protects the antenna, maintains scanning performance through the patterned region, and provides partial reflective functionality through the non-patterned region. This multi-functionality eliminates the need for additional compensating antennas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The patterned mirror enhances the beamforming antenna's performance by allowing beams to pass through, maintaining the mirror's functionality and improving communication coverage, especially in 5G systems, without the need for additional antennas, thus optimizing efficiency and cost.
Implementation Method 1
a pattern formed on a mirror may maintain an inherent function of the mirror and also enhance the performance of a beamforming antenna by allowing a beam of the beamforming antenna to pass through the pattern
