Customized Antenna

Customized GSM Quaq-Band Antenna for Personal Emergency Tracking Device

1) Green Antenna carried out the 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
5) Antennas for mass production 
 The final customized antenna design is submitted and approved by customer.

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

Antenna Metal Stamping Tools and Samples

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

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.
 

Antenna Design Support - Plastic Tooling

We provide plastic tooling and mock up sample to support client's production. 

2G Quad Band Antenna Design for Personal Communication Device

The antenna was designed with following frequency bands:
 
 

1. 850 Band (824MHz- 894MHz)

2. 900 Band (880MHz - 960MHz)

3. DCS Band (1710MHz-1880MHz)

4. PCS Band (1850MHz- 1990MHz)

 

Two prototype builds were run.  Measurement of 3D efficiency and S11 were performed on each prototype.  TRP and TIS measurement were also included.  Final design was submitted and approved by client.

Mockup Samples for Antenna Design

Green Antenna provided mockup samples for the designed antenna.  The mockup sample includes metal stamping and carrier.  

Patient Bed Tracking System At KK Women and Children's Hospital

Green Antenna is to design a system with Communication range at 150m line of sight with conducted power at 10dBm and conducted sensitivity at -108dBm.  
We design the antenna at  the bottom of DUT  and print it on the PCB.   Low pass filter was added  to reduce EMC issue.  Design simulation was performed by SEMCAD X.  Design was successfully deployed.  Test data was collected with both  Pro-type and actual PCB measurement.  
 

GSM Quad Band and GPS Antenna Design For Track Fleet Tracking System

The project required 3 different types of antennas:
1.  GSM Quad band antenna.
2.  GPS antenna.
3.  433MHZ antenna.  
 
Green Antenna carried out all the necessory step of feasibility study, simulation, prototyping and validation.  

All In One Antenna (WWAN, BT, WIFI, 2XMIMO) For Warehouse and Cargo Fleet Tracking System

Green Antenna was responsible for the antenna design for this deivce.   2 different kinds of antenna was required:
 
1.  All in One antenna which includes WWAN, Blue Tooth, WIFI, 2XMIMO.  This includes:

  • 3G Penta-band antenna, including GSM 900/850/1800/1900, WCDMA Band 1, II, V, VIII (2100, 1900, 850, 900) and CDMA 850/1900.
  • BT alone Antenna 2402 MHZ to 2484 MHz.
  • WIFI 2XMIMO antenna

2.  Blue Tooth plus WIFI combo antenna.  This includes:
