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

Customized 3G/GSM and MIMO Wifi Antenna for Truck Tracking Device

Green antenna provide full service from feasibility study to prototype build.
1) Green Antenna carried out Antenna feasibility study and Antenna Simulation
2) Antenna prototype samples for each design phase and prototype build
3) Passive and active antenna measurement for every design phase
4)  Devices OTA test measurement report for each design phase
 
 Final design is submitted and approved by customer. Customer is satisfied with the performance of both the Penta-band  and WIfi MIMO antenna.
 

OTA Measurement For WiFi and Blue Tooth Combo Antenna

Green Antenna carried out the measurement for this Wifi plus Blue Tooth antenna, at Frequency Bands of:
 
WIFI 802.11bgn and Blue Tooth 2402Mhz to 2484Mhz.
WIFI 802.11an - 4900MHz to 5840MHz
Data of Antenna Efficiency and Antenna Rediation Pattern was collected and delivered to customer.
