In some instances the anisotropy is a principal feature of the design materials, as is the case with biased ferrite substrates. Axial ratio is the ratio of orthogonal components of an electric field. Both the number of papers and the topics of the papers are examined. In software simulations, there is one parameter called axial ratio through which the type of polarization is iden-tified. 1 2 Abstract The purpose of this thesis is going to design a microstrip antenna that can detect the different tissue, according to this clue, we suppose that it can be used in medical application, for example to detect the breast tumor. Covering theory, design and modeling techniques and methods, this source book is an excellent reference tool for engineers who want to become more familiar with microstrip antennas and microwave systems. 1 Fig. NPTEL provides E-learning through online Web and Video courses various streams.
