Resumé

This paper shows how to efficiently reduce the electromagnetic energy around the speaker area of mobile phones in order to fulfil the HAC standard. Since a mobile phone is more likely to fulfil the HAC requirements below 960 MHz than at higher frequencies the main focus of this paper is on reducing the NFs above 960 MHz. In particular, devices operating in the Personal Communications System (PCS) band is considered. The transmit band (1850-1910 MHz) of PCS (PCSTX) is the most critical for HAC.
