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
