Objectives:

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

Report effectively with a range of audiences.

Figure 1. An example coaxial cable is shown. 'A' denotes the outer insulator. 'B' denotes the outer conductor.

'C' denotes the inner insulator. 'D' denotes the inner conductor.

Lab 6 Instructions:

a) Investigate using a coaxial cable to create a center-fed half-wavelength dipole antenna with a length of about

2.45 inches (i.e. dipole length). Assume the coaxial cable has an SMA connectors.

b) Write a report for Lab6. A sample Lab6 report outline is below:

1.

Introduction/Team Members/Team Members Contribution

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) as described below. Include a figure caption(s), annotations, etc. for your

block diagram(s).

A. Create sketches illustrating the assemble/build steps for a design of center-fed half-wavelength dipole

antenna with a length of about 2.45 inches (i.e. dipole length).

B. Sketch the current distribution for a center-fed half-wavelength dipole antenna.

III. Data Analysis and Interpretation

A. Calculate the length in cm of your center-fed half-wavelength dipole antenna design.

B. Calculate the free-space frequency corresponding to a wavelength of 4.90 inches.

C. Discuss bandwidth of your center-fed half-wavelength dipole antenna design.

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 Lab6 report. Each student creates their own Lab6 report.

d) In Canvas, upload your Lab6 report (i.e. pdf, doc, or docx) to LAB6 (See Tab -> Canvas Assignments) by its Canvas due

date.
