Inclined Dielectric Array Antenna for Wider Beamforming Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current millimeter-wave antenna devices for 5G mobile networks have limited radiation coverage areas due to restricted beamforming bandwidth, which affects communication transmission range and network device layout.
Innovation Solution
The array antenna design includes inclined dielectric elements and radiators, increasing the beamforming bandwidth by mirroring dielectric elements and radiators along a center line, allowing for expanded radiation coverage through inclined surfaces and parts, thereby enhancing the radiation coverage area.

Engineering Contradiction Analysis
1Area of stationary object
If conventional planar dielectric elements are used, then the antenna structure is simple, but the radiation coverage area is limited
Solution Approach 1:
The patent transitions from planar (2D) dielectric elements to three-dimensional (3D) inclined dielectric elements. The first and second dielectric elements are configured with inclined surfaces that form specific angles with the ground plane, creating a three-dimensional structure that expands the radiation coverage area beyond what conventional planar antennas can achieve.
Solution Approach 2:
The antenna is divided into multiple discrete components: first and second dielectric elements with inclined surfaces, first and second radiators positioned on different surfaces, and a ground plane. This segmentation allows each component to be optimized independently while working together to achieve expanded coverage.
2Area of stationary object
If beamforming bandwidth is increased to expand radiation coverage, then the radiation coverage area improves, but the device complexity increases
Solution Approach 1:
The first and second dielectric elements are configured with asymmetric inclination angles relative to the ground plane. This asymmetric arrangement creates diverse radiation patterns and expands the beamforming bandwidth by utilizing different angular orientations for beam formation, thereby increasing radiation coverage without requiring complex additional components.
