Course Goals

The course uses EM field principles in conjunction with network theory to obtain efficient means for analyzing and designing of microwave subsystems and antennas, which are the part of modern microwave communication systems.  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.  Modern 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 the part of modern wireless communication systems and radar. The design of antennas using antenna CAD software is demonstrated. Principles of experimental characterization of microwave sub-systems and antennas are also presented.

It is expected that upon successful completion of the course, students will:

• understand the principles of operation of typical passive and active microwave circuits and antennas that are essential to modern communication technologies
• know how to design simple microwave circuits including directional couplers, detectors, mixers, switches and amplifiers, as well as know how to design wire and patch antennas and arrays  
• be able to verify the design techniques learned in the course by using modern microwave and antenna CAD packages.

Graduate Attributes Developed

The University of Queensland has defined a set of graduate attributes to specify broad core knowledge and skills associated with all undergraduate programs (http://www.uq.edu.au/hupp/contents/view.asp?s1=3&s2=20&s3=5). This course addresses these attributes as follows:

 

Assumed Background

Pre-requisite: ELEC3100 + MATH2000. Inc. COMS7104 or 3E404, Rec. P: ELEC3200 (or equivalent that concerns Principles of Semiconductor Devices).
The course assumes that the students are familiar with the following concepts and terms: travelling and standing voltage and current waves, equivalent circuit parameters of a TEM transmission line, impedance/admittance and reflection coefficient presentation on the Smith Chart, Maxwell equations and expressions for a field radiated  by a Hertzian dipole. Also assumed is the basic knowledge of semiconductor devices such as diodes and transistors to better understand the operation of active microwave devices.

Assessment

COMS4104/7104 will be assessed by several methods as outlined below. Your final grade (on a 1 to 7 scale) will be determined by combining the marks from the various assessment components as described below. For each assessment item, reference is made to the specific learning objectives (from the list above) which the assessment item will address.

TOTAL MARK (100) = 2-ASSIGNMENTS (16) + 3-LAB REPORTS (24) + 1-MID-SEMESTER TEST (10)+ FINAL EXAM (50). A non-zero mark must be obtained from each of these FOUR components to be considered for the final assessment.

·         COMS7104 students are asked to use Serenade Harmonica in addition to PUFF in their assignment and labs reports.

·         Also, there are different break points for  grades 1,2 and 3. 

Assignments

Dates for submission of the 2 Assignments and the 2 Laboratory Reports are shown in the above table. The submission should be made via the Submission Box posted in the GPS by 5pm on the date indicated above. All details concerned with the format of Assignment and Laboratory Reports will be posted on the WEB and explained by the tutor during the Tutorial and Lab sessions. Also the mark allocation for each part of the Assignment or Lab Report will be clearly indicated on the Lab/Project WEB site. In general, the Assignment and Lab Reports reflect the student ability to perform a professional engineering design and including proper presentation of the results obtained by using available CAD software package.

Tutorial Exercises

A number of quantitative problems relevant to the covered lecture material will be solved during tutorial sessions. Students are encouraged to attempt them prior to tutorials in order to exercise their own understanding of the lecture material. Solutions to these tutorial problems will be of significant help in obtaining solutions to the 2 Tutorial Assignments and the 3 Laboratory Pracs scheduled in this course.

Final Examination

A two hour final examination will be held during the final examination period. This exam will be closed-book and will contain both multiple-choice/short-answer/essay questions.  The exam format is expected to be similar to that of tutorial assignments carried out during the semester. You may bring a battery-operated non-programmable calculator. Programmable calculators and other computing or communication devices are NOT permitted. You will require a HB or 2B pencil and an eraser to complete the exam.

Note: Assessment variation is possible for students with a disability.

Note: Students may request the use of dictionaries, including bilingual dictionaries, supplied by Examinations Section. 

Determination of Final Grade

Final mark for COMS4104 students will be calculated from your marks for the assignment, the two class tests, the mid semester and end of semester exams. Your final grade is then computed from the final mark using the following table:

final mark	grade
85-100	7
75-84	6
65-74	5
50-64	4
45-49	3
20-44	2
0-19	1

For COMS7104 students: grade 3 (47-49%), grade 2 (30-46%), grade 1 (0-29%).  

1. Serious Fail
Fails to satisfy most or all of the basic requirements of the course.

2. Fail
Fails to satisfy some of the basic requirements of the course.

3. Pass Conceded
Falls short of satisfying all basic requirements for Pass but can be granted concession for deficiencies through:

·         being close to satisfactory overall, or

·         having compensating strengths in some aspects of the course, or

·         having compensating strengths in other courses, or

·         other mitigating considerations.

4. Pass
Satisfies all of the basic learning requirements for the course, such as knowledge of fundamental concepts and performance of basic skills; demonstrates sufficient quality of performance to be considered satisfactory or adequate or competent or capable in the course.

5. Credit
Demonstrates ability to use and apply fundamental concepts and skills of the course, going beyond mere replication of content knowledge or skill to show understanding of key ideas, awareness of their relevance, some use of analytical skills, and some originality or insight.

6. Distinction
Demonstrates awareness and understanding of deeper and subtler aspects of the course, such as ability to identify and debate critical issues or problems, ability to solve non-routine problems, ability to adapt and apply ideas to new situations, and ability to invent and evaluate new ideas.

7. High Distinction
Demonstrates imagination, originality or flair, based on proficiency in all the learning objectives for the course; work is interesting or surprising or exciting or challenging or erudite.

Each passing grade subsumes and goes beyond the grades lower than it.  At the discretion of the lecturers, final grades may be scaled upwards but not decreased.
