Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antenna modules for 5G mobile communication technologies face challenges in achieving high radio wave radiation efficiency in various directions, particularly due to low radiation efficiency in specific orientations, such as when patch antennas face the rear cover or dipole antennas face the side surface of electronic devices.
Innovation Solution
The proposed antenna module design includes a housing with a first and second plate and a side member, featuring an antenna substrate with multiple antennas positioned to radiate waves effectively in different directions. The antenna substrate has a first surface facing the first plate, a second surface facing the second plate, and a third surface facing the side member, with the wireless communication circuit applying feeding signals to ensure beam coverage towards the side surface, utilizing a configuration of first, second, and third antennas with specific distances from the third surface to enhance radiation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna module is used, then the device complexity is reduced, but the radio wave radiation efficiency in various directions deteriorates
Solution Approach 1:
The antenna module is segmented into three distinct antennas (first antenna, second antenna, third antenna) positioned at different distances from the third surface. Each antenna contributes to radiation in different directions, with the first and second antennas providing rearward radiation and the third antenna providing lateral radiation, thereby achieving omnidirectional coverage without requiring multiple separate antenna modules
Solution Approach 2:
The patent transitions from a two-dimensional antenna arrangement to a three-dimensional configuration by positioning antennas at different depths (first distance, second distance, third distance from the third surface). This vertical dimensionality allows the antenna module to radiate effectively in multiple directions simultaneously, solving the directional coverage problem while maintaining a single compact module
2Reliability
If multiple antenna modules are used to achieve wide radiation coverage, then the radio wave radiation efficiency in various directions is improved, but the mounting space increases
Solution Approach 1:
The patent merges the functions of multiple antenna modules into a single integrated antenna module. By combining three antennas with different orientations and positions within one module, it achieves the wide radiation coverage that would otherwise require multiple separate modules, thereby reducing the total mounting space while maintaining radiation efficiency
Solution Approach 2:
The antenna module employs a nested arrangement where the third antenna is positioned between the first and second antennas at a smaller distance from the third surface. This nested configuration allows multiple antennas to be compactly integrated within a single module, maximizing space utilization and achieving omnidirectional radiation without increasing overall module volume
