Slot Antenna Board Coupling Without Dedicated RF Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for electrically coupling a slot antenna to a radiofrequency communication circuit face challenges such as difficulty in assembly, increased size, and cost due to the use of dedicated connectors like pogo pins, and inconsistency in connection placement.
Innovation Solution
A radiofrequency connection portion is integrally formed with a metal plate containing a slot antenna, providing a deformed structure that mechanically and electrically engages with a connection portion on the radiofrequency communication board, eliminating the need for separate connectors and ensuring consistent, robust connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated connectors such as pogo pins are used to electrically connect the slot antenna to the RF circuit, then the electrical connection is established, but the volume of the system increases and the cost increases
Solution Approach 1:
The patent merges the connector function with the metal plate structure itself. The connection portion is integrally formed with the metal plate through deformation, eliminating the need for separate dedicated connectors like pogo pins. This integration reduces system volume while maintaining electrical connection reliability between the slot antenna and RF circuit.
Solution Approach 2:
The metal plate serves multiple functions: it provides structural support, forms the slot antenna, and includes a deformed connection portion that provides both mechanical support and electrical connection. This multi-functionality eliminates the need for separate connectors and reduces overall system volume.
2Reliability
If wired connection is used between the slot antenna and the circuit, then the electrical connection is established, but the assembly difficulty increases due to requiring two separate elements to be held and soldered
Solution Approach 1:
The connection portion is integrally formed with the metal plate as a single piece through deformation processes. This eliminates the need for separate wiring and soldering operations, significantly simplifying assembly while maintaining reliable electrical connection between the slot antenna and RF circuit.
3Reliability
If float jump wires are used to connect the RF circuit and the housing surface, then the electrical connection is established, but the assembly difficulty increases
Solution Approach 1:
The connection portion is formed as an integral part of the metal plate through deformation, creating a rigid and reliable connection structure. This eliminates the complexity of assembling float jump wires while maintaining electrical connection reliability.
4Reliability
If separate connectors are used to connect the slot antenna to the RF circuit, then the electrical connection is established, but the signal loss increases
Solution Approach 1:
The connection portion is integrally formed with the metal plate, creating a continuous conductive path with minimal joints or interfaces. This integration reduces signal loss compared to separate connectors while maintaining reliable electrical connection for RF signals.
