Ansoft Corporation recently acquired Compact Software. This new development offers a win-win relationship among Ansoft, Compact, and — most important — the microwave/wireless circuit design industry. Ansoft wins advanced linear and nonlinear circuit simulation; Compact wins enabling electromagnetic (EM) simulation technology; and the microwave industry wins a clear, viable and comprehensive sol...

The chapter deals with the techniques used for the design, fabrication and measurement of antennas. The design and simulations are performed using the FEM based Ansoft High Frequency Structure Simulator (HFSS). The antennas are fabricated using photolithographic method.VNA HP8510C and Agilent PNA 8362B are used to measure antenna characteristics such as return loss, radiation pattern, gain etc....

In this paper we present our efforts in characterizing and optimizing the influence of a Wafer-Level Packaging (WLP) solution on the electromagnetic behaviour of RF-MEMS devices. To this purpose, a fully parameterized FEM model of a packaged Coplanar Waveguide (CPW) is presented in order to optimize all the technology degrees of freedom (DoF’s) made available by the fabrication process of the c...

We present a comparison of RF simulations with Ansoft HFSS and CST Microwave studio software, for a commercially available 7 T multi-channel coil. We investigated the conditions influencing precision and simulation time. When simulation parameters (such as mesh size) are appropriately selected and full coverage of the results is ensured, there is agreement between simulated and experimentally d...

In order to obtain the influence of different structures and frequencies on thrust cylindrical permanent magnet linear synchronous motor, transient simulation magnetic field motor is carried out by using Ansoft software, correctness verified experiments. Through simulation, characteristics under voltage frequency, air gap size, width its are obtained.
