Toward the design of tightly coupled parallel dipoles arrays in the presence of the Human body, based on port impedance characteristic modes

Abstract

In this paper a phased array consisting of eight tightly coupled parallel dipoles is studied. The array is placed adjacent to the human body in an attempt to define the effects of its dielectric constant and losses on the array design. The analysis of the array is carried out with characteristic modes. The ultimate scope of this effort aims at the establishment of an orthogonal eigencurrent basis, which will be exploited in the synthesis of desired radiation patterns. Its novel aspect refers to the pattern synthesis in the presence of lossy Human body.
