Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF communication systems face challenges in efficiently handling multiple frequency ranges, particularly in integrating and optimizing the transmission and reception of signals across Frequency Range 1 (FR1) and Frequency Range 2 (FR2) in 5G networks, which can lead to inefficiencies in bandwidth utilization and signal strength.
Innovation Solution
The integration of a frequency range two antenna array into a frequency range one antenna system, utilizing a four by four array of planar inverted-F or mesh patch antennas, with dedicated signal conditioning circuits for each frequency range to manage and adjust gain and phase for beamforming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used to handle both FR1 and FR2 signals, then device complexity is reduced, but signal handling capability and frequency coverage are limited
Solution Approach 1:
The antenna system is designed with multi-functionality where a single integrated antenna structure can handle both FR1 and FR2 frequency ranges. The antenna includes an FR1 antenna element and an FR2 antenna array that operate together as one unified system, allowing the device to support multiple frequency ranges without requiring separate antenna systems for each band.
Solution Approach 2:
The patent combines the FR1 antenna and FR2 antenna array into a single integrated antenna system. The FR2 antenna array is integrated into the FR1 antenna structure, creating a unified antenna assembly that can simultaneously or separately operate in both frequency ranges, thereby reducing overall device complexity while maintaining versatility.
2Adaptability or versatility
If separate antenna systems are used for FR1 and FR2, then frequency coverage is improved, but device complexity and space requirements increase
Solution Approach 1:
The FR2 antenna array is nested within or integrated into the FR1 antenna structure. This nesting arrangement allows the smaller FR2 array elements to be incorporated into the larger FR1 antenna assembly, enabling both frequency ranges to be supported within a single compact antenna system rather than requiring separate independent antenna structures.
Solution Approach 2:
The patent transitions from a single-element antenna to a multi-element array structure for the FR2 band, integrating it within the FR1 antenna. This dimensional expansion from simple antenna to array configuration enables broader frequency coverage while maintaining a unified structural approach that manages complexity.
3Reliability
If an antenna array is integrated into the FR1 antenna, then beamforming capability is improved, but manufacturing complexity increases
Solution Approach 1:
The antenna system is segmented into distinct functional components: the FR1 antenna element and the FR2 antenna array. Each segment is designed and optimized for its specific frequency range, allowing for specialized manufacturing approaches for each part while maintaining overall system integration. The FR2 array consists of multiple individual elements that can be manufactured separately and then assembled into the final integrated structure.
