Solution Overview
Problem
Current antenna modules face challenges in achieving wide coverage and small size to support high-frequency signals for 5G communications, particularly in efficiently integrating broadside and edge fire antennas on a single substrate to enhance communication performance.
Innovation Solution
The antenna module integrates a broadside antenna array and an edge fire antenna array on the top and side surfaces of a dielectric substrate, respectively, using a conductive layer and dicing process to form the antennas, which reduces fabrication costs and increases coverage area without increasing the substrate size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple antennas are integrated on a single substrate to achieve wide coverage, then coverage area is improved, but device size increases
Solution Approach 1:
The patent applies dimensionality change by forming antennas on multiple surfaces of the dielectric substrate - specifically the top surface and the side surface. This three-dimensional antenna integration allows the antenna module to achieve wide coverage area without increasing the planar footprint of the substrate, effectively resolving the contradiction between coverage area and device size.
2Reliability
If complex antenna integration processes are used to achieve dual radiation directions, then antenna performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the formation processes of multiple antennas by using a common conductive layer deposited on the dielectric substrate. This single conductive layer is subsequently patterned to create both the first antenna on the top surface and the second antenna on the side surface, thereby achieving dual radiation direction antennas while simplifying the manufacturing process and reducing production steps.
3Ease of manufacture
If conventional antenna fabrication methods are used, then manufacturing process is simple, but fabrication cost increases
Solution Approach 1:
The conductive layer in the patent serves multiple functions simultaneously - it forms both the first antenna on the top surface and the second antenna on the side surface. This multi-functional use of a single conductive layer reduces the total amount of conductive material required and eliminates the need for separate antenna fabrication processes, thereby reducing overall fabrication costs while maintaining manufacturing simplicity.
