Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna designs require separate space for different wireless communication frequency bands, leading to excessive space occupation when multiple communication technologies are applied.
Innovation Solution
A multi-band antenna with multiple feed points is designed, utilizing a substrate with a main body and branched bodies connected via coaxial cables to generate radio frequency signals across various frequency bands, allowing a single antenna to transmit signals for different frequency bands simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate antennas are designed for different frequency bands, then communication capabilities for different wireless technologies are improved, but space occupation increases excessively
Solution Approach 1:
The patent combines multiple antenna functions into a single integrated antenna structure that supports multiple frequency bands (2.4GHz and 5GHz) through a unified design, eliminating the need for separate antennas for different wireless technologies
Solution Approach 2:
The single antenna is designed with multi-functionality to support multiple frequency bands and wireless communication standards simultaneously, allowing one antenna to perform the roles that previously required multiple separate antennas

AI summary
A multi-band antenna with multiple feed points includes a substrate, a main body, a branch body, a first and a second coaxial cable. The main body and the branch body are disposed on the substrate and respectively have a first and a second signal feed point. The first coaxial cable has a first outer conductor connected to a grounding layer and a first core conductor connected to the first signal feed point for feeding the first signal feed point with a first signal, so that the main body generates a RF signal of a first frequency band. The second coaxial cable has a second outer conductor connected to the main body and a second core conductor connected to the second signal feed point for feeding the second signal feed point with a second signal, so that the branch body generates a RF signal of a second frequency band.
