Abstract :
Operating with multi-frequency and simultaneously mitigating the EMW hazard in the handset mobile telephone is the aim of this paper. To achieve this goal three arrays are constructed, each array, which contains three elements, corresponding to a different operating frequency. The operating frequencies chosen were 966.8 MHz, 1861 MHz and 1980 MHz. This choice enables the mobile to be compatible with different worldwide operating systems namely GSM-900, DCS-1800, PCS-1900 and DECT. The dimensions of each array and hence the power radiation pattern shall contribute greatly towards mitigating the hazard caused by the EM field radiated usually from the mobile set antenna
