An Electrical Beam Tilt Array Antenna for Mobile Base Stations

A base station antenna is an RF component capable of critically affecting performance of a cellular system. Down tilting base station antennas is used in mobile communication to prevent co-channel interference. In this paper, we introduce antenna configuration for electrical downtilt. Here a genetically optimized technique is employed. Printed circuit dipoles are employed as radiation elements.

Mobile phone base stations-Effects on wellbeing and health.

Studying effects of mobile phone base station signals on health have been discouraged by authoritative bodies like WHO International EMF Project and COST 281. WHO recommended studies around base stations in 2003 but again stated in 2006 that studies on cancer in relation to base station exposure are of low priority. As a result only few investigations of effects of base station exposure on heal...
