  1. Measurement HFSS™ Adaptive Wireless Systems Dept. of Electronic Eng. Cork Institute of Technology aws@cit.ie How shielding works Introduction: Used to provide electromagnetic shielded environment for RF/Microwave measurements to be conducted without unwanted interference. RF Measurement Laboratory Why? 1) Exclude unwanted electromagnetic radiation or signals in order to allow sensitive electrical measurements to be carried out. 2) To contain radiating signals which can disrupt neighbouring equipment. Reflecting &Absorbing radiation Shielding reduces signals to levels where they no longer interfere with measurements or cannot be received. Software RF Measurement Equipment • HP VEE Pro 6 • - Data acquisition • Designer • RF circuit simulator • HSPICE • -Mixed signal Circuit Simulator • Ensemble • - 2.5D EM simulator • HFSS • - 3D EM simulator • Agilent 8714ES Vector Network Analyser • Agilent 86100 Infinium Wideband Oscilloscope • Time Domain Reflectometry Module • Anritsu Spectrum Analyser • Agilent ESG Signal Generator Applications • Characterisation of various IC packages and interconnects. • The design of an ultra wideband transceiver. • Miniaturisation of transceivers. • Creation of IBIS models. This equipment and software has been successfully used to date in a range of RF applications: • To evaluate and model RF passive chip components to size 0402 and embedded passives such as spiral inductors. • Characterisation of RF transistors for use in amplifiers. • Simulation and Analysis of RF Filters. Comparsion of simulation & measurements Sample Applications MCM-L Design of a miniaturised transceiverdeveloped using measurement and simulation Design of a Waveguide Tee junction using HFSS S11 (Return Loss) S21 (Insertion Loss) • S-parameter response of microstrip interconnect extracted using: • HFSS Electromagnetic Simulator • Measurement using VNA
