• Homework 20%

Test I: 20% (CLOSED BOOK) (Thursday, Feb. 15)

Test II: 20% (CLOSED BOOK) (Thursday, April 5)

Final Exam: 30% (CLOSED BOOK) (Tuesday, 3:30pm, 05/01/01)

Design Project: 10%

• The letter grade assignment is based on the following scale: from 100 to 90 pts. => A, from 89 to 80 pts. => B, from 79 to 70 pts => C, from 69 to 60 pts. => D, from 59 to 0 pts. => E.
• The student is responsible for all business conducted during any scheduled class period. Any revision to the test dates, homework assignments, etc. will be made during the class period.
• Failure to take exams: Make-up exams will be given in cases where the student contacts the instructor prior to the exam and receives permission to make the test up.
• The lectures will follow the text. The student is expected to read the text and is responsible for all material in the reading assignments.

TOPICS:

1. Overview: Maxwell Equations review, Computational considerations
2. Radiation, dipole, far fields, radiation patterns, directivity and gain, reciprocity principle, input impedance, polarization, communication application of antennas
3. Small loop antennas
4. Line sources
5. Dipole Antennas, monopoles, antennas over ground, numerical methods for wire antennas
6. Array antennas, array factor, pattern multiplication, array directivity, broadband antennas
7. Aperture antennas

OUTCOME:

The following competancies should be imparted to the students:

1. An understanding of radiation of electromagnetic waves.
2. Ability to characterize the radiation properties of various antenna types.
3. Ability to decide on what antenna to choose for a given communication link scenario.
4. The ability to design various types of antennas.
5. Basic knowledge of how to test antennas.
6. Skill to perform elementary antenna analysis on a computer.

COMPUTER USAGE:

The students are expected to be familiar with at least one of the computer languages or computer math packages such as Matlab to complete some homework problems and the projects. Students should sign up for computer accounts in the Engineering Workstation Laboratory (EWL).

LABORATORY:

The students construct at least one antenna per given specifications. The radiation characteristics are measured and compared to design values.

ABET CATEGORY:

Engineering Science: 2 credits (67%), Engineering Design: 1 credit (33%)

COMPUTER ASSIGNMENT: To be announced in class.

DESIGN CONTENT:

The design project concerns design aspects of wire-type antennas. The students are required to perform the initial designs with empirical design formulas. The design is refined using a sophisticated PC antenna analysis code. The students then construct their antennas and their performance is measured at the Lexmark, International, Inc.'s EMC laboratory. The students are then required to do a formal report summarizing their design and discussing non-ideal performance aspects of their antennas.
