Radio Frequency and Microwave

The research related to emerging technologies such as Internet of Things (IoT) holds paramount importance across the globe as of today.

Radio Frequency and Microwave

Welcome to RF&M

The RF&M group at NUST SEECS

SEECS offers doctorate, postgraduate, undergraduate, and certificate level Programmes that owe their emergence to the relentlessly growing demand of professionals with expertise in Information Technology. These Programmes have been planned to offer a blend of computers, communication technologies and other information retrieving/processing tools in order to provide the youth with the practicable skills to enter the world of opportunities and capitalize on the huge IT market of the 21st century. SEECS continuously seeks to stay in forefront as a centre of academic and research excellence. SEECS offers MS and PhD in Electrical Engineering with special focus on Radio Frequency (RF) & Microwave domain since 2010. The school works closely with industrial partners on joint Research & Development and consultancy projects. The school holds state-of-the-art facilities for the design, fabrication and testing of microwave circuits and antennas. It possesses unique microwave measurement capabilities such as Anechoic Chamber for antenna testing, Electromagnetic Compatibility /Electromagnetic Interference Lab for electromagnetic compatibility and immunity measurements and PCB fabrication lab. The key facilities are used in teaching and research, as well as utilized for services to other academic and industrial partners.</

Anechoic Chamber

This facility is used to characterize antennas in the frequency range from 0.8GHz to 40GHz. The Anechoic Chamber is equipped with a near-field planner scanner and a far-field tower to measure the radiation pattern of a given antenna under test (AUT). The measurement software has the capability to transform the near-field data to far-field data for plotting antenna radiation patterns in 3-D. In addition, antenna arrays, Radar cross-section (RCS) measurements of RFID tags and other applications where isolated environment is required can be supported by the anechoic chamber.

Test Rate:

The lab offers services to the academic and industrial organizations in measuring the radiation patterns and gain of various kind of antennas. The typical Antenna Pattern and Gain Measurement test (Antenna Characterization) cost is Rs 80,000/- (4-6 hours testing). For specialized testing which may require large data points, changes in the chamber etc., the cost will be estimated based on the number of hours required for the job.

Introducing Our Team

Electromagnetic Compatibility / Electromagnetic Interference (EMC / EMI) Lab

This lab aims at imparting EMC/EMI knowledge to students and researchers both from NUST and other universities and organizations. In addition, the facility is utilized to provide EMC/EMI pre-compliance testing of commercial products. Presently, the lab has the capability to perform testing as per European standards including Conducted Emissions, Radiated Emissions, Radiated Immunity, Harmonic & Flicker, Electrostatic Discharge and Surge, Burst & Power Fail test. The mission of the lab is to provide EMC/I testing, consultancy and training services for local industry & academia to promote indigenous development of electronic products made in Pakistan.
