Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication using multiple antennae in a single wavelength band, variations in signal intensities can occur, limiting communication speed and range due to the antenna with the lowest signal intensity, affecting overall performance.
Innovation Solution
The antenna device comprises a first and second antenna aligned such that the amplitude directions of their radio waves coincide, with each antenna connected to a respective RF circuit and baseband processing circuitry, allowing for coordinated communication and improved signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple antennae are arranged to communicate in one wavelength band, then communication bandwidth is increased, but signal intensity variation occurs limiting communication performance
Solution Approach 1:
The patent applies local quality by configuring each antenna with specific amplitude directions tailored to its position and function. The first antenna is configured with a first amplitude direction and the second antenna with a second amplitude direction, allowing each antenna to have optimized local radiation characteristics rather than uniform configuration, thereby reducing signal intensity variation while maintaining wide bandwidth communication
Solution Approach 2:
The patent resolves the contradiction by introducing amplitude direction as an additional dimension of control. Instead of only controlling signal intensity magnitude, the invention controls both the magnitude and directional characteristics of each antenna's radiation. This dimensional expansion allows simultaneous achievement of wide bandwidth and consistent signal intensity across multiple antennas
2Adaptability or versatility
If antennae are arranged to cover wider wavelength band, then communication capacity increases, but communication speed and range are limited by the weakest antenna
Solution Approach 1:
Each antenna is configured with specific amplitude directions optimized for its role in the multi-antenna system. The first antenna has a first amplitude direction and the second antenna has a second amplitude direction, allowing each to contribute effectively across the wide wavelength band without any single antenna becoming a bottleneck for communication speed
Solution Approach 2:
The invention changes the amplitude direction parameter of each antenna to optimize overall system performance. By adjusting and controlling the amplitude directions of individual antennas, the system achieves both wide wavelength band coverage and maintains high communication speed, preventing any single antenna from limiting overall performance
