Balanced antenna was proposed to improve the wireless communication performance by reducing platform noise. The concept was implemented and demonstrated using a balanced antenna design and ceramic balun. Platform noise reduction was achieved up to 5 dB and 11 dB for broadband noise and narrowband noise respectively. It is promising to improve the throughput and range by employing the balanced antenna in laptop computer.

A fully functional internal DTV diversity antenna has been designed and tested. The proposed internal balanced dipole antenna was integrated with a DTV module in a notebook computer. The results demonstrate that a balanced dipole antenna for noise suppression and diversity reception enable high quality reception of a DTV signal even though we trade-off some antenna performance after packaging in notebook computer.
