Abstract

The increased demand of mobile communication capacity in India, has resulted in an increase in construction and existence of cellular base station facilities in public neighborhood over recent years. They are generally considered as hazardous because of the electromagnetic radiation originating from these facilities. This has led to public concern regarding the safety and possible adverse health effects of human exposure to microwave energy emitted by these facilities. The aim of this paper is to present some preliminary measurement techniques to find the amount of electromagnetic radiation absorbed by human being living in the vicinity of multiple base station antenna towers, operating at different carrier frequencies.

Abstract

Microstrip antennas have attracted a lot of attention due to rapid growth in communications area. Several patch designs with single feed, dual frequency operation have been proposed recently. This paper tries to explain the limitation of microstrip antennas in multiband operations and also explains the need of having planar inverted F antenna. The papers analysis the importance of variations in dimensions of planar inverted F antenna. Simulations are done to understand the operational changes that occurs due to slight variations in antenna dimensions. From the study it can be understand that a slight variation in dimension of any key parameter will influence the working of mobile hand set.
