ECE 4940/ECE 7940 Antenna Theory, Design and Laboratory

Module LAB3. Antenna Patterns

30 Points

Objectives:

Set up antenna experiment, analyze/interpret data, and use engineering judgment to draw conclusions.

Report effectively with a range of audiences.

Lab 3 Instructions:

a) Four antenna normalized power pattern equations are given below:

1. cos' where 0° ≤0≤90°,0 ≤ ≤360°

2. cos² 20 where 0° ≤0 ≤90°,0° ≤ ≤360°

3. sin² where 0 ≤0 ≤90,0 ≤ ≤360°

4. sin² 20 where 0° ≤0≤90°,0° ≤ ≤360°

Investigate the four antenna patterns given above.

b) Write a report for Lab3. A sample Lab3 report outline is below:

Introduction/Team Members/Team Members Contribution

I.

Paragraph(s) should introduce the laboratory, team member names, contributions of each team

member, etc. (If a member doesn't contribute, then simply list their contribution as none. You

will not lose points for the other team members lack of contributions.)

II. Block Diagram Sketch of Experiment

Create a block diagram(s) or sketch(s) of the lab experiment. Include a figure caption(s),

annotations, etc. for your block diagram sketch.

An example generic block diagram sample without details is shown below:

(i.e. details need to be added for your lab, e.g. Input Data Variables are 0 and $):

Plot/nIII. Data Analysis and Interpretation

A. Include any design equations that are used in the lab.

B. Include any variables names and values that are used in the lab.

C.

Plots of each antenna pattern generated using visualization/data analysis tool of your

choice (e.g. Normalized pattern versus 9). Label plots thoroughly (e.g. Title, x-axis label,

y-axis label, units, etc.).

D. Compare and contrast the patterns (e.g. Maxima/Minima locations, shape, etc.).

E. Discuss the considerations and practices for plotting the patterns, which are not ø

independent.

IV. Conclusions

Paragraph(s) summarizing what you learned/discovered in the lab experience. Considering the

concepts learned during this course, draw conclusions.

c) Create a file (i.e. pdf, doc, or docx) of your Lab3 report. Each student creates their own Lab3 report.

d)

In Canvas, upload your Lab3 report (i.e. pdf, doc, or docx) to LAB3 (See Tab -> Canvas Assignments)

by its Canvas due date.
