Design Tools

AWR Design Environment


Both undergraduate and postgraduate teaching is conducted using AWRDE V11 Design. In addition to laboratory and class room use, the license server provides home access to registered students for completing their laboratory classes off working hours. Forty users can simultaneously access the software.

Ansoft HFSS/Designer


In addition to AWR Design Enviorenment, the laboratory also uses Ansoft HFSS and Designer mainly for research and project work.


Measurement Facilities

Microwave Network Analyser


The laboratory is equipped with an Agilent 8719ES vector network analyser for measurements up to 13.5 GHz. Shown in the figure is the Agilent Network analyser interfaced to a PC for automated measurement. A test fixture and a 3.5mm calibration kit can also be seen in the picture.

R.F. Network Analysers


In addition to AWR Design Enviorenment, the laboratory also uses Ansoft HFSS and Designer mainly for research and project work.


Spectrum Analysers


The R.F./microwave measurements are also supplemented by two Anritsu Spectrum Analyzers. The picture above shows a R.F. synthesised source connected to a spectrum analyser in a CNR measurement experiment.

Noise figure meter and the calibrated hot/cold noise source


Shown in the picture is the calibrated noise source connected to the noise figure meter to calibrate the instrument.


Fabrication Facilities

Microwave and R.F. circuits are fabricated in-house using the facilities of the PCB Fabrication laboratory of the department. The equipment in the PCB laboratory has been carefully selected to meet the high accuracies demanded by microwave applications. These include the LPKF-S63 PCB milling machine with a 100 micron accuracy and the Photoplotter with a 50 micron accuracy.

A sample of fabricated circuits

Shown below are a collection of circuits fabricated as part of the EE554 Microwave Techniques course. This is an undergraduate course of 3 credits with a 30 hour laboratory component. All the following circuits are designed for a center frequency of 5 GHz.

Lowpass filter


Branch line coupler



Rat-race coupler


Wilkinson's power divider




The picture below shows a more advanced circuit, the R.F board of frequency synthesiser for generating signals from 500 MHz to 8 GHz. This project was funded by the Telecommunications Regulatory Commission (TRC), Sri Lanka.
