The book includes the remarkable information of use of nano-crystalline Mg-Cd and Nd3+substituted Mg-Cd ferrites as substrates for microstrip patch antenna. The details of ferrites synthesis by oxalate co-precipitation method under microwave sintering were well explained. Overall detailed explanation of results obtained from synthesis, characterization using XRD, FE-SEM, EDAX and FT-IR technique and magnetic properties of ferrite materials was described. The explanation of effect of microwave sintering of structural properties of ferrite was given precisely. The details measurements of permittivity, dielectric loss tangent, permeability, magnetic loss tangent, reflection loss of ferrites were also included. The design of microstrip patch antennas on synthesized ferrite using these electromagnetic parameters with help of Ansoft Designer SV2 software was described. The procedure of fabrication of substrates of ferrite, printing of silver patches on ferrite substrates and connection of SMA connectors at proper locations was given in this book. Finally this book explains information about analysis by simulation and measurements of antenna parameters on vector network analyzer.
The ability of microwave and millimeter wave radiation to detect biological agents, with a particular focus on anthrax spores, has been investigated. The characterization measurement technique for powder dipicolinic acid sample up to 170 GHz is based on standard waveguide configuration. A variety of network analyzer systems and scalar analyzer systems have been developed and applied to make the transmission and reflection measurement from X band to D band. No resonance has been found in dipicolinic acid. A multilayer CPW sensor has been designed to test the liquid sample such as keratin, DNA and bacteria subtilis solution up to 40 GHz. Simulation and numerical calculation help to separate the radiation loss from the total loss, therefore, the dielectric properties can be deduced from the extracted dielectric loss. Measurements of liquid samples like ethanol, methanol and water have a good compatibility with theoretical prediction. The ultimate objective is to find the resonances then apply high power microwave at those frequencies to kill the spores "locally" based on the nonthermal heating mechanism.
Within this Project, the main goal is to find the approximate values of the parasitic elements for 0805 SMD resistors and capacitors as well as 0603 SMD resistors and capacitors when operated on higher frequencies. To achieve the required task, the substrate RT/duroid 5870 (Rogers Corporation) with a printed copper transmission line on it, was used. This transmission line was cut in the middle and the SMD components were fixed on that gap by soldering at both sides. This model was then placed on a solid copper box and attached to the Network Analyzer with the help of connectors. The measurements were taken within the frequency range of 50 MHz and 10 GHz and transferred from the Network Analyzer to the computer (attached to the Network Analyzer) with the help of the ADS (Advanced Design System) software. Finally, compatible circuit models (for resistors and capacitors) were created in ADS by considering all the parasitic elements and the recorded measurements (respective S-parameters) were matched and optimized by using the fitting technique as well as by the different features of ADS.
A major revolution in wireless industry is now due, with the development of Ultra-Wideband, Cognitive Communication, and Networking. The goal of this book is to do spectrum occupancy and wideband channel sounding using automated system. In this book, the automated systems developed using LabVIEW as a tool to control Spectrum analyzer, Vector Network Analyzer (VNA), and Digital Sampling Oscilloscope (DSO) are discussed. Spectrum occupancy for CDMA, GSM, Wi-Fi, and DTV spectrum s is investigated, followed by field strength measurements for DTV signal. Frequency domain and Time domain channel sounding are also performed and all results are shown.
