Millimeter-Wave Antenna Layout for 5G Communication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices supporting 5G require efficient millimeter-wave band communication, but existing designs face challenges in fully exploiting the performance of millimeter-wave band communication circuits due to space constraints and power consumption limitations, especially when using submillimeter-wave and millimeter-wave bands.
Innovation Solution
A communication device with a flexible layout that includes multiple millimeter-wave band communication antennas distributed across various surfaces and bodies, allowing for enhanced flexibility and precise beamforming, and incorporating an obstacle detection sensor to optimize power usage by only activating millimeter-wave communication when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If millimeter-wave band communication antennas are provided in a single body, then the device structure is simple, but the layout flexibility is limited and antenna performance cannot be fully exploited
Solution Approach 1:
The communication device is divided into multiple bodies (first body and second body), with millimeter-wave band communication antennas distributed across different bodies. This segmentation allows each antenna to be optimally positioned in its respective body, improving layout flexibility and signal reception while maintaining relatively simple individual body structures.
2Reliability
If multiple millimeter-wave band communication antennas are provided, then the communication performance is improved, but the device complexity increases
Solution Approach 1:
Multiple millimeter-wave band communication antennas are distributed across multiple bodies rather than concentrating them in one location. This segmentation approach improves communication performance through better spatial diversity and signal reception while keeping each individual body's structure relatively simple and manageable.
