Loop -Type Parasitic Radiator For Back Radiation Suppression In Mobile Handset
Abstract
Abstract— Cellular personal communications system has marked a phenomenal and intensive development and its cons has
been observed lately and time and over sidelined. Thus the protection towards a person's head and safeguarding from the
radiations of non-ionizing electromagnetic signals produced by cellular phones while in use is fetching one of the most
concerned task to neutralize to an infinitesimally small amount. Since Planar Inverted F Antenna (PIFA) is a very favoured
design in mobile applications, it is of prime importance to analyze the matching properties of such an antenna in real
application scenarios (close to the head, grasped by the hand). Any matching deviation leads to the reduction of radiated
power which should be accounted for in the system design. Different specifications of the proposed antenna are measured
through simulations in free space as well as in the presence of the human head model. Specific Absorption Rate (SAR) is
also computed for this antenna and the interaction of the antenna with the human body is also investigated. All simulations
are performed using the CST Microwave Studio. The results of elaborated antenna design which have minimized radiation
towards the user’s head are presented in this paper
