The report of  report with return-loss , 3D efficiency and 3D radiation pattern was submitted to client.

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.
