Wireless Module Antenna Integration Signal Decay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices experience significant signal decay due to long cable resistance, leading to reduced sensitivity and performance, especially when the wireless communication module and antenna are remotely located on a main board.
Innovation Solution
Integrating the antenna directly onto the wireless communication module's circuit board or using a flexible circuit board to reduce signal transmission distance, with the antenna being electrically connected through via holes or embedded within the module, thereby minimizing signal decay and enhancing module sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication module and antenna are disposed at remote places on the main board, then the transceiver performance can be improved, but the signal decay increases significantly due to long cable resistance
Solution Approach 1:
The patent merges the wireless communication module and antenna into an integrated module, eliminating the need for long cables connecting separate components. The antenna is directly mounted on the circuit board of the wireless communication module, reducing signal transmission distance and resistance-induced decay while maintaining transceiver performance.
Solution Approach 2:
The patent transitions from a planar layout where the antenna is remotely disposed on the main board to a three-dimensional integrated structure where the antenna is mounted vertically or at an angle on the wireless communication module's circuit board, reducing the effective signal path length through spatial optimization.
2Reliability
If the wireless communication module and antenna are disposed at remote places on the main board, then the transceiver performance can be improved, but the occupied space on the main board increases
Solution Approach 1:
The patent combines the wireless communication module and antenna into a single integrated unit, reducing the total occupied space on the main board compared to having them as separate remotely disposed components connected by cables.
Solution Approach 2:
The antenna is nested within or mounted on the wireless communication module structure, allowing compact integration where the antenna utilizes the same space envelope as the module housing rather than requiring additional separate space on the main board.
3Reliability
If the wireless communication module and antenna are disposed at remote places on the main board, then the transceiver performance can be improved, but the power dissipation increases due to cable resistance
Solution Approach 1:
The patent merges the wireless communication module and antenna into an integrated module, eliminating the cable connection that causes resistive power dissipation. The antenna is directly electrically connected to the module's circuit board, minimizing the conductive path and associated energy losses.
