Microwave engineering and antenna systems

Within the domain of electrical engineering there is a growing interest in microwave engineering and antenna systems. Next to traditional application areas, such as wireless and radar, microwave engineering and antennas have become eminent in several new application domains, such as medical applications (e.g. MRI scanner), 5G wireless communications and high-speed IC and PCB design. The course includes hands-on lab using state-of-the-art design tools and measurement equipment (Network Analyser).

Content

  • Introduction in RF systems: Link-budget analysis component specification
  • Transmission lines and related components
  • Introduction into microwave amplifiers
  • Lab 1: Simulation tools
  • Lab 2: Network analyser

Learning objectives

  • Be able to calculate the link budget for a basic RF system, including the loss in the propagation channel according to Friis equation.
  • Be able to derive the main component specifications for a basic front-end of a transmitter and receiver.
  • Be able to explain the basic effects of noise and distortion on the RF amplifier performance.
  • Be able to use transmission line concepts, e.g. matching circuits, transformers and power dividers.
  • Be able to design an RF circuit in a transmission-line based design tools.
  • Design a conjugate matched amplifier and a small-signal amplifier for given transistor S-parameters, taking the amplifier stability into account.
  • Be able to explain the technical challenges of a power amplifier and explain how high output power can be achieved even for low breakdown voltage transistors.
