DIY Directional Antennas 2024 – Final Reflection

Objective:

I can complete the DIY Directional Antenna Project by reflecting on and evaluating what I learned throughout the course of the activity by completing an online reflection form.

Links:

Google Classroom

Topics Discussed:

Wireless Networking
802.11 Wi-Fi spec
Directional Antennas
Waveguide Antenna

Assignment:

Today, we will complete our directional antenna project. Our goal was to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m) with a minimum signal strength of -67 dBm.

All of the cantennas tested performed respectably, and for some reason 8th period’s cans vastly outperformed 3rd period! We can speculate why later, but overall one came out on top with a very respectable -57 dBm signal and sustained 45% signal quality over a distance of 100 yards! Please congratulate Denis & Brizalin for their outstanding tin can waveguide antenna assembly that conquered all other designs. By comparison, 3rd period’s best can was a respectable (but not record-breaking) -65 dBm with a 35% signal quality, produced by the team of Carlos & Phoenix. They will all be enjoying pizza and wings for lunch today as the rest of the class completes this final reflection assignment.

The link for the reflection assignment can be found here. Please follow the instructions on the form, and answer each question group with a paragraph comprised of at least three complete sentences. Pay attention to your spelling, punctuation and grammar as you compose your paragraphs. This assignment is to be written in a professional tone in an academic voice, and it will be graded based on the criteria described on the form. Each team member must submit their own form, but can work together on the wording of the individual submissions.

You are encouraged to type your answers in a separate Google Doc to ensure your answers are saved, then transfer your answers to the Google Form for submission. This assignment is effectively your final project assessment which represents the major portion of your project grade, and should be addressed accordingly.

Good luck, and thank you for all your hard work on this project, and throughout the second term. Do your best on your reflection and then enjoy some hard-earned rest and relaxation with your families during the Thanksgiving four-day weekend! Rest well, because we’ve got some big decisions and important work to do when we return to Networking and Cybersecurity in December!

Yagi Antenna

Assignment:

Today, we will continue the build phase of our directional antenna project. Remember that the goal is to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m).

All tools and equipment are on the metal carts and tables in the front of Room 225. The transmitter testing cart is in the front of Room 225, and the username and password is on a sticky note on top of the cart. Use the velcro strap to secure your can to the tripod and use the tripod handles to angle your can to point at the upright antennas on the target router located on the receiver cart. The receiver cart (with the target router) is in the back of the room, and the username and password is located on a sticky note on the PC case.

Please use this time to make progress on your project. When you are ready for testing, I will set up the testing carts on both ends of the hallway outside my room in the 200 building so we can test all completed antennas to allow those with working products to see the results and modify their designs if necessary. You should have a finished antenna prepared to test at that time so you can tweak the design if necessary before the final test on the week of the 18th!

We will conduct final tests on Tuesday, November 26th. To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a -67 dBm wireless signal over a 100 yard distance (the length of the football field).

Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest signal strength (as measured by Signal Quality percentage and Signal as measured in decibels) over the longest distance on the final testing day will receive a personal pizza and wings party, to be held while everyone else writes a three paragraph personal reflection on Wednesday, November 27th describing their participation in this project.

Good luck, and remember: Your antenna doesn’t have to be perfect, it just has to be better than everyone else’s!

  • Directional Antennas
  • Waveguide Antenna
  • Yagi Antenna
  • Flickenger design Antenna

Assignment:

Today, we are going to begin a focused short-term project that is to be completed before the Thanksgiving Holiday. The goal is simple: design and build a directional antenna that will sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m).

The stretch goal is a little more complex: design and build a directional antenna that will extend that 2.4 GHz Wi-Fi signal as far as possible.

  1. Use the links I have provided to learn about do-it-yourself directional antenna designs. There are many designs to choose from, so do your research and select the design that you think will be most effective in extending and sustaining the Wi-Fi signal over the longest range.
  2. You may work with a partner, or choose to go it alone. If you choose to work with a partner, you will need to download, complete and turn in both a Project Team Agreement and a Project Team Work Plan (available via the links provided above).
  3. Even if you are working by yourself, use the Project Team Work Plan to identify and prepare for the steps of this project (i.e. research, acquisition of materials, installation, configuration, building, testing, modification and upgrades).
  4. Upload your completed Project Team Agreement Form and Project Team Work Plan Form to today’s assignment post on our Google Classroom as soon as they are completed. The completed Project Team Contract and Project Team Work Plan are due by the end of the class on Friday, November 15th.
  5. Proceed with the first identified steps in your Project Team Work Plan. Do your best to follow the plan, but don’t be afraid to amend or alter the plan as the need arises.
  6. Tools and equipment will be provided, and all work should be completed in Room 225. You will need to notify the instructor if you need access to any additional tools located in Room 212. Testing PCs (sender and recipient) will be provided on rolling carts to allow for testing of antennas.
  7. Please use this time to make progress on your project. We have time provided to complete the project, but no time to waste. It is highly likely that your first antenna design will not work as well as you expect it to, and you will need time to test and make adjustments to your design to achieve optimal results. Use the time given to build, test, modify and retest to get the best results!
  8. We will conduct initial tests the week of November 18th. To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a -67 dBm wireless signal over a 100 yard distance (the length of the football field).
  9. Upon completion of initial tests, you will have time to revise and retest your design before the final testing on Tuesday, November 26th.
  10. The team (or individual) that produces the antenna that can reliably sustain the highest signal strength over the longest distance on the final testing day will receive a personal pizza and wings party, to be held while everyone else writes a three paragraph personal reflection on Wednesday, November 27th describing their participation in this project.

Good luck, and remember: the best way to eat an elephant is one bite at a time.
