Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in 5G communication systems using the ultrahigh frequency (mmWave) band is the strong linearity and low diffraction of radio waves, leading to reduced antenna gain with increasing horizontal distance, which restricts point-to-point communication between devices unless antennas are precisely aligned.
Innovation Solution
An antenna device with a first member and a second member having a hole or groove, where the antenna module is positioned, allowing for a predetermined separation distance to induce electromagnetic waves, enabling uniform omnidirectional radiation and communication without alignment requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If antennas are placed close together in integrated small antenna designs, then device size and power consumption are improved, but antenna gain is sharply reduced as horizontal distance increases
Solution Approach 1:
The patent transitions from horizontal antenna arrangement to vertical stacking arrangement, utilizing the third dimension (height) to separate antennas. This dimensional change allows antennas to be positioned close together horizontally (improving device size) while maintaining sufficient separation vertically (preserving antenna gain through increased distance separation).
Solution Approach 2:
The patent employs curved surfaces and spherical geometries in the antenna structure, including curved reflecting surfaces and spherical antenna elements. This curvature enables omnidirectional radiation patterns and improves signal propagation in multiple directions, maintaining communication reliability despite reduced horizontal separation distances.
2Reliability
If antennas are positioned at fixed positions for point-to-point communication, then communication reliability is improved, but alignment requirements become restrictive and reduce versatility
Solution Approach 1:
The patent implements adjustable and reconfigurable antenna positioning mechanisms that allow dynamic adjustment of antenna orientation and position. This enables the system to adapt to different communication scenarios and maintain reliable point-to-point communication without requiring precise fixed alignment, thereby improving both reliability and versatility.
Solution Approach 2:
The patent designs antenna structures with omnidirectional radiation capabilities and multiple functional surfaces that can serve different purposes. The curved reflecting surfaces and multi-element arrays enable the antenna to function effectively in various orientations and communication modes, reducing alignment restrictions while maintaining communication reliability across different scenarios.
