This course uses electromagnetic principles to present the theory & operation of simple circuit devices & antennas at microwave frequencies, which are the part of modern microwave communication equipment. The emphasis is placed on planar guiding & radiating structures that enable either hybrid &/or monolithic integration of the devices. Modern CAD software packages are introduced & demonstrated through simulations of microwave networks & antenna configurations.

The course uses electromagnetic (EM) field principles in conjunction with network theory to obtain efficient means for analysing and designing microwave subsystems and antennas, which areᅠ part of modern microwave communications systems including Mobile and Satellite Systems .ᅠ

In the first part of the course, the emphasis is placed on planar guiding structures that enable either hybrid and/or monolithic integration of microwave devices.ᅠ Modern computer-aided design (CAD) software packages are introduced and demonstrated through simulations of microwave passive and active devices and sub-systems.

The second part of the course is devoted to the analysis and design of antenna elements and arrays which are part of modern wireless communications systems and radar. The design of antennas using antenna CAD software is demonstrated. Some experimental works are then conducted in the Microwave Lab to verify the main fundamentals of microwave design.

Task description

This assessment task evaluates students' abilities, skills and knowledge without the aid of generative Artificial Intelligence (AI) or Machine Translation (MT). Students are advised that the use of AI or MT technologies to develop responses is strictly prohibited and may constitute student misconduct under the Student Code of Conduct.

The Practical part of the course will include the following components:

0) Introductory Session to Microwave CAD

In this introductory session, the students will receive information about the microwave CAD tools that will be used in the practicals.

(Weight: 3%)

1) Practical 1: TLs & Impedance Transformers

This part of the lab project aims to test your knowledge and design skills of microwave transmission lines and impedance transformers. You will be asked to design different types of TLs and transformers with the use of a microwave CAD package. A report providing the basis for assessment of your performance should include the computed results (including prints of the computer screen) and discussion.

(Weight: 9%)

2) Practical 2: Hybrid Circuits

This part of the lab project aims to test your knowledge and design skills concerning microwave hybrid circuits and PIN diode phase shifters. You will be asked to design various types of hybrids and PIN diode phase shifters, and asses their performance with the use of a microwave CAD package. A report, forming the basis for the assessment of your performance, should include the computed results (including prints of the computer screen) and discussion.

(Weight: 9%)

3) Practical 3: Analysis and Design of Antennas

This part of the lab project will test your knowledge and analysis and design skills concerning antennas. You will be asked to design and assess the performances of individual antennas using microwave CAD tools. A report, forming the basis for the assessment of your performance, should include the computed results (including prints of the computer screen) and discussion.
