Microwave Devices and Components
Remcom's XFdtd software is well-suited for any microwave device design or analysis task.
Whether the application is waveguides, power dividers, filters, couplers, or the like, XFdtd can provide quick, efficient, and accurate EM simulation results.
An antenna based on a transverse slotted rectangular waveguide design is realized in a substrate integrated waveguide structure and simulated in XFdtd EM Simulation Software.
This example uses XFdtd to simulate the performance of a low cost, chipless RFID system. The RFID tag is comprised of two ultrawide band monopole disk antennas mounted in a cross-polarized configuration combined with a microstrip line adjacent to six varying size spiral resonators which each represent a single bit in the RFID tag code. The system is validated using two cross-polarized log periodic dipole arrays as the send and receive devices.
Simulation of rectangular waveguides which are bent to create mode converters including TE20-TE10 and TE40-TE10.
XFdtd is used to analyze a Rotman Lens.
Remcom's XFdtd software is well-suited for any microwave device design or analysis task. Our Waveguide Examples booklet showcases a collection of five different waveguide applications with downloadable project files.
This paper demonstrates the design of Rotman lens for ESM sensor application in operation band 32-38 GHz. The initial design is created in Remcom’s Rotman Lens Designer and then verified against experimental measurements. Parameters of the realized prototype are presented and methods of increasing its performance are outlined.
Simulation can greatly enhance the design and prototype process when developing new products. This is especially true for the design of waveguide devices, such as a cavity filter, as the engineer can quickly calculate a number of key metrics leading to an optimal configuration. Through optimization via scripting, exceedingly fast processing using a GPU, and waveguide ports, this presentation demonstrates some of XF’s features for the design, optimization, and analysis of waveguide devices.
A brief overview of Remcom's Rotman Lens Designer.
In this video, a Remcom engineer walks through the steps to set up and tune a Ku Band microstrip lens in Rotman Lens Designer (RLD). Included is a discussion of the various options for exporting the file and importing into XFdtd EM Simulation Software, including the use of a customized script to automatically set up the ports and include the material properties.
This video is a tutorial that shows a rectangular waveguide being built using XF’s modeling techniques. You will learn how to use XF’s built-in materials library, create the waveguide interface, solve for and display lowest-order TE modes, and display the field results.
This short video clip highlights the waveguide ports feature in XF.
