Credits: 4

UW Course Catalog Description

Coordinator: Yasuo Kuga, Professor of Electrical Engineering

Goals: To expose students to antenna analysis, design, fabrication, and testing using simulation tools and microwave equipment.

Learning Objectives:

At the end of this course, students will be able to:

• Understand the properties of different antennas such as radiation pattern and gain of dipole, microstrip, horn and Yagi antennas.
• Analyze the characteristics of the microstrip antenna (MSA) using different models including lumped element, TL, and cavity models.
• Analyze MSA excitation using the resonator model and 1-D Green’s function.
• Understand the antenna types used in modern cell phones including inverted-F and meanderline antennas.
• Design MSA using design tools such as Ansoft Designer and HFSS.
• Design and test the linear array antenna using monopoles.
• Design, fabricate and test printed antennas including printed Yagi antenna.

Course Structure: The class meets twice a week. Six HW and lab assignments are given over the quarter. Midterm exam is given during the quarter covering antenna theory and applications. Final exam covers the quarter comprehensively. Final project deals with design, analysis, fabrication, and testing of different antennas. One example is the printed Yagi antenna.

Computer Resources: PCs capable of running Ansoft Designer and HFSS

Laboratory Resources: Antenna range in Rm419, network analyzer

HW and Lab assignments:

1. Design of simple MSA Requires Matlab
2. Antenna measurements Antenna range in Rm419
3. Design of probe fed MSA Requires Designer or HFSS
4. Green’s function for cavities
5. Design of MSA with impedance matching Requires Designer or HFSS
6. Array antenna design and measurements Antenna range in Rm419
7. Final project Requires HFSS and antenna range

Grading: HW and Lab (20%), Exams (10%), Final Project (70%). Graduate students will have additional homework and project requirements focused on analysis and simulation.

Outcome Coverage:

(a) An ability to apply knowledge of mathematics, science, and engineering. The homework and exams require direct application of mathematics, scientific, and engineering knowledge to successfully complete the course. This requires performing various numeric and integration tasks and attaching engineering meaning to the numeric results. (H)

(b) An ability to design and conduct experiments, as well as to analyze and interpret data. Students will investigate antenna designs using computational electromagnetics tools such as Designer and HFSS (H).

(c) An ability to design a system, component or process to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability and sustainability. Lab assignments and final project deal with a particular design problem to be solved. (H)

(d) An ability to function on multidisciplinary teams. (N/A)

(e) An ability to identify, formulate and solve engineering problems. The course provides sufficient knowledge so that students can conduct detailed design for the final project. Although the fabrication process is crude compared to the industry standard, the simulations and testing parts are similar to that of industry. (M)

(f) An understanding of professional and ethical responsibilities. This is covered in some lectures (L)

(g) An ability to communicate effectively. Lab assignments and final project will require detailed reports. (M)

(h) The broad education to see the impact of engineering solutions in a global and societal context. Students taking the course will realize the broad applicability of antennas in modern society through communications, navigation, and remotes sensing. (L)

(j) Knowledge of contemporary issues. Antennas used in modern cell phones are discussed. The effect of human hand on the antenna performance is included. (M)

(k) An ability to use the techniques, skills, and modern engineering tools necessary for engineering practice. Students are asked to design antennas using Ansoft Designer and HFSS which are widely used in industry. Students will also use the antenna range and network analyzer to test antennas. (H)
