Customized PCB Wifi Antenna for SD Memory Card


The challenges faced in the design of such antenna are the limited antenna volume and the severe loading from nearby metallic structures. The design is optimized using simulation tool prior to prototype modeling and measurement. Antenna efficiency of 38% is achieved in actual operating environment when the memory card is placed inside a camera.


Green Antenna provided the follow services to customer


1) Wifi Antenna feasibility study and Simulation on SD Card

2) Antenna prototyping on SD card's PCB board

3) Passive antenna Measurement

4) Antenna measurement report


Full discussion of this design is available in this IEEE paper.  

Movable RF Absorber Wall

Green Antenna built a movable wall for client.  The wall was built on a movable base, with microwave absorber material on surface.  Client may move the wall to appropriate location of their lab to carry out accurate test and measurement.

Supply RF Measurement Parts to Client

We sourced and supplied to client required parts, including power splitter, indoor  cables and various SMA connectors.  

Antenna Metal Stamping Tools and Samples

Green Antenna provided clients with Matal Stamping Tools and off-tool samples.

Antennas test fixture for manufacturing test system
