Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mmWave antenna modules face challenges in achieving high gain and bandwidth due to size constraints, particularly in mobile devices where antennas are positioned on the outermost side, leading to performance deterioration as they are miniaturized to fit larger screens and slimmer profiles.
Innovation Solution
A dielectric resonator antenna design that includes a first and second dielectric material block stacked with a bonding layer, a feeder, feed pattern, and an antenna patch, optimized to increase relative dielectric constants and reduce conductor loss, allowing for improved gain and bandwidth without increasing antenna size.

Engineering Contradiction Analysis
1Volume of moving object
If the antenna module size is reduced to fit larger screens and slimmer profiles, then the device form factor is improved, but the antenna gain and bandwidth performance deteriorate
Solution Approach 1:
The patent increases the relative dielectric constant of the dielectric material block to enhance the gain and bandwidth of the antenna without increasing its physical size. By changing the material parameter (dielectric constant) rather than the geometric parameters, the antenna achieves improved performance within the constrained size envelope required for modern mobile devices with larger screens and slimmer profiles.
2Length of moving object
If the antenna module is miniaturized, then the device profile is slimmer, but conductor loss increases leading to performance degradation
Solution Approach 1:
The patent addresses conductor loss in miniaturized antennas by optimizing the dielectric material parameters and structural configuration. By increasing the relative dielectric constant and carefully designing the feed pattern and antenna patch geometry, the patent reduces the impact of conductor loss that typically escalates in smaller antennas, thereby maintaining efficiency despite the reduced dimensions.
