Absorbed Power Minimization in Cellular Users with Circular Antenna Arrays
AIP Conference Proceedings(2010)
摘要
Nowadays electromagnetic pollution of non ionizing radiation generated by cellular phones concerns millions of people In this paper the use of circular antenna array as a means of minimizing the absorbed power by cellular phone users is introduced. In particular, the different characteristics of radiation patterns produced by a helical conventional antenna used in mobile phones operating at 900MHz and those produced by a circular antenna array, hypothetically used in the same mobile phones, are in detail examined Furthermore, the percentage of decrement of the power absorbed in the head as a function of direction of arrival is estimated for the circular antenna array
