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.
