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

Client Background: 
Client is a SGX (Singapore Stock Exchange) listed public company, a global leader in contract manufacturing and technical solution provider. The client company has strong expertise in printing, imaging, storage, RF communication, measurement and medical equipments.
Client Requirement: 
Client designed a tracking device for warehouses and cargo vehicles. The device shall be able to communicate with Wifi, Blue Tooth, 3G network and MIMO.
Project Synopsis: 

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:

  • WIFI 802.11 abgn and BT shared Antenna
  • WIFI 802.11bgn and BT - 2402MHz to 2484MHz
  • WIFI 802.11an - 4900MHz to 5840MHz.

We carried out feasibility study, simulation, prototyping and validation.   The final design structure was provided in step file for client's pilot run PCB fabrication and mechanical engineering design.   The antenna's radiation efficiency, radiation pattern, return loss and isolation was included in the design report.  

Project Starts: 
June, 2009 to January, 2010
