Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio frequency mobile communication antennas face challenges in achieving a compact design with multiple radiators while maintaining cost efficiency, as vertical distribution networks require numerous components.
Innovation Solution
The antenna design incorporates a base body with angled walls that support a distribution network, allowing feeding lines to be placed vertically, reducing size without increasing parts, and uses a single-piece base body with a metallic conductive structure for efficient manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distribution network is arranged vertically to achieve compact design, then the antenna size is reduced, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The patent merges the distribution network components by providing the walls with both the feeding lines and the ground portion integrated into them. The walls serve dual purposes as both structural support and as the distribution network components, eliminating the need for separate components and reducing assembly complexity while maintaining compact vertical arrangement.
2Ease of manufacture
If molded interconnected devices are used to reduce manufacturing cost, then production efficiency increases, but the antenna size increases
Solution Approach 1:
The patent transitions from planar distribution networks to three-dimensional vertical arrangement by providing the feeding lines and ground portion on the walls extending vertically from the cover portion. This dimensional change allows compact antenna size while maintaining integration suitable for cost-efficient manufacturing processes.
3Volume of moving object
If the feeding lines and ground portion are provided on the walls, then the antenna size is reduced and components are minimized, but signal interference may increase
Solution Approach 1:
The patent segments the walls into multiple portions, with each wall portion dedicated to specific functions (feeding lines on one surface, ground portion on another surface). This segmentation allows proper spacing and orientation between feeding lines and ground portions, reducing electromagnetic interference while maintaining compact vertical integration.

AI summary
An antenna has a base body and a metallic conductive structure applied to the base body, wherein the base body comprises a flat cover portion and walls extending perpendicularly away from the cover portion. The conductive structure has at least one radiator provided at the cover portion, at least one feeding line for the at least one radiator and at least one ground portion, wherein the feeding line and the ground portion are provided at at least one of the walls. The radiator defines a radiator plane (R) and the feeding lines extend in at least one feeding plane (F), wherein the at least one feeding plane (F) is arranged perpendicularly to the radiator plane (R). Further, an antenna array and a mobile communication base station are shown.
