Chassis Antenna Layout for Multi-Band Coverage With Fewer Cut-Outs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chassis antennas for wireless devices require multiple cut-outs to cover multiple frequency bands, which detract from the visual appeal and structural strength of the device.
Innovation Solution
A chassis antenna formed at least in part by a dielectric gap between the chassis and the antenna, with one end defined by a cut-out and the other end conductively connected to the chassis, and a coupled feed capacitively coupled to the modem, allowing for multiple frequency bands with fewer cut-outs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cut-outs are used in the chassis to cover multiple frequency bands, then the antenna can support multiple frequency bands, but the visual appeal and structural strength of the chassis deteriorates
Solution Approach 1:
The patent merges multiple antenna elements into a single integrated chassis antenna structure. Instead of creating separate cut-outs for different frequency bands, the invention uses one continuous antenna element that can operate across multiple frequency bands, thereby maintaining chassis integrity while achieving multi-band functionality.
Solution Approach 2:
The chassis antenna is designed with multi-functionality to cover multiple frequency bands (e.g., Wi-Fi, Bluetooth, cellular) using a single antenna element. This universal design eliminates the need for multiple specialized cut-outs, preserving both the visual appeal and structural strength of the chassis while supporting diverse wireless communication standards.
