The paper presents the design of a novel ultra-wideband microwave crossover for the use in microstrip circuits. The proposed structure includes a double microstrip-coplanar waveguide (CPW) vertical interconnect in single-layer substrate technology which allows an inclusion of a finite-width coplanar waveguide (CPW) on the top side of the substrate to achieve the required cross-link. The present...

A new technique for three-dimensional (3D) electric-field (e-field) vector measurement is presented. Three laser beams with different propagation paths in an electro-optic (EO) crystal were used to resolve 3D components of e-field vectors. We adopted a special geometric shape of bismuth silicon oxide EO crystal so that the three beams would propagate within it. A sensitivity of 0.6 V/cm square ...

This paper focuses on the EM modeling of an inkjet printed humidity sensor for UHF RFID systems originally presented in [1]. EM modeling is used to predict the sensor readings as well as to design the tag for certain operating frequencies. Therefore accurate EM modeling is crucial. This paper presents a comparison between three different types of EM solvers in modeling of the humidity sensor; A...

Developed by Ansoft in 1990, the High Frequency Structure Simulator (HFSS) has become the simulator of choice for the electromagnetics design of complex threedimensional microwave devices. HFSS has been used to design thousands of microwave devices more quickly and reliably than is possible with prototypes alone. This broad use has generated considerable user feedback and customer requests for ...

This design uses Ansoft HFSS software. Where the simulation results frequency 2.4 GHz obtained return loss value -22.28 dB, -19.03 dB -14.94 for GHz, VSWR 1.17 1.25 3, 7 1.43 GHz.Gain 1 directivity 2,33 dB. The show that parameter...

The Substrate Integrated Waveguide (SIW) technology is an attractive approach for the design of high performance microwave and millimeter wave components, as it combines the advantages of planar technology, such as low fabrication costs, with the low loss inherent to the waveguide solution. In this study, a substrate integrated waveguide power divider, circulator and coupler are conceived and o...

In this paper, dual-rotor permanent magnet induction motor(DRPMIM) is studied to improve performance of usual induction motor(IM). Two-dimensional finite element model for DRPMIM is established by Maxwell Ansoft software, and electromagnetic characters of that was analyzed.Based on the rotating coordinate system, the mathematical model concerning DRPMIM, performance curves under the different l...

A probe-fed circularly polarized 3-layer stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of three patches and three substrates. The lower and middle patches are of square-shaped where as the upper patch is of triangular-shaped. One slot is inserted in the lower layer, two slots are inserted in the middle layer a...

As wireless communication applications require more and more bandwidth, the demand for wideband antennas increases as well. For instance, the ultra wideband radio (UWB) utilizes the frequency band of 3.1–10.6GHz.This paper presents a work carried out within ULTRAWAVES in the area of antenna design and analysis. A new multilayer microstrip antenna is introduced using Stacked Multiresonator patch...
