Spotlight On Waveguides
Simulating A Beam Scanning, Substrate Integrated Waveguide, Leaky Wave Antenna In XFdtd

In this example, XFdtd is used to simulate the performance of a substrate integrated waveguide (SIW) leaky wave antenna with transverse slots.

Introduction To Waveguide Connectors And Uni-Guide

The waveguide, along with the coaxial line, is one of the most important transmission media in any modern RF, microwave, and millimeter-wave component, subassembly, and system. In mmWave bands, it is especially true that the waveguide is widely used, and engineers will pay high attention to loss. 

Putting FPGAs To Work In Software Radio Systems

This handbook introduces the basics of FPGA technology and its relationship to SDR (software-defined radio) systems. A review of Pentek’s GateFlow FPGA Design Resources is followed by a discussion of features and benefits of FPGA-based DDCs.

Overview Of Tests On Radar Systems And Components

This application note demonstrates how to use the Rohde & Schwarz radar product portfolio to tackle test and measurement tasks in modern radar technology. The idea is to become familiar with radar issues as well as learn how to solve certain test and measurement tasks.
