Advanced Design System:
Advanced Design System (ADS) is the world’s leading electronic design automation software for RF,
Microwave and high speed digital applications. In a powerful and easy-to-use interface, ADS pioneers the
most innovative and commercially successfully technologies such as x-parameters and 3D EM simulators
used by leading companies in the wireless communication & networking and aerospace & defense
industries. For WiMAX, LTE, Multi-gigabit per second data links, radar & satellite applications. ADS
provide full standards-based design and verification with wireless libraries and circuit-system.
Advanced Design System is an electronic design automation software system produced by Keysight EEsof
EDA a division of Keysight Technologies. It provides an integrated design environment to designers
of RF electronic products such as mobile phones pagers, wireless
networks, satellite communications, radar systems, and high-speed data links.
Keysight ADS supports every step of the design process—schematic capture, layout, design rule
checking, frequency-domain and time-domain circuit simulation, and electromagnetic field simulation—
allowing the engineer to fully characterize and optimize an RF design without changing tools.
Keysight EDA has donated copies of the ADS software to the electrical engineering departments at
many universities and a large percentage of new graduates are experienced in its use. As a result, the system
has found wide acceptance in industry.
ADS are the leading electronic design automation software for RF, Microwave and high speed digital
applications. It helps uncover and resolve integration issues early in the design process before fabrication
of wireless components. 1mil=0.0254cm

Lab 2: Design and Simulation of Single Stub circuits
A load impedance of  10j15ZL is connected to a 50Ω transmission line. Find the size and
placement of the matching stub that will remove all the standing waves and match the load to the line.
Also draw its electrical diagram and physical connection. Use single stub shunt tuner with open circuited
stub in your design. Verify you result using ADS
