Directional Antennas
Waveguide Antenna
Yagi Antenna
Helical 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. Many of the Pringles can yagi antenna designs struggled with this task, but one came out on top with a very respectable -66 dBm signal and 34% sustained signal quality over a distance of 100 yards. Please congratulate Erwin N. and Brandon A. for their outstanding Pringles can yagi antenna assembly that conquered all other designs. They will 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. Do your best on your reflection and then it’s back to the TestOut LabSim software to finish up our last few chapters before Winter Break!

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 cart 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 piece of tape on the side 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 stickynote on the PC case.
Please use this time to make progress on your project. On Friday, November 21st, 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 25th!
We will conduct final tests on Tuesday, November 25th. 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 quality signal (as measured by Signal Quality percentage and Signal as measured in decibels) over the longest distance will receive a personal pizza and wings party, to be held on Wednesday, November 26th while everyone else writes a four paragraph personal reflection 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.

Assignment:
Today, we are going to begin a focused short-term project that is to be completed before the Thanksgiving Break. 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.
Good luck, and remember: the best way to eat an elephant is one bite at a time.

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). Many of the antenna designs successfully completed this task, but only one came out on top with a whopping -68db signal and 32% sustained signal quality over a distance of 150 yards. Please congratulate Luis and Eli for their outstanding helical antenna design that conquered all other designs. They will be enjoying pizza and wings on Friday as the rest of the class completes the 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 complete five-sentence paragraph. 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. 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. Do your best on your reflection and then it’s back to the lab for some Linux installation and configuration exercises!

Assignment:
Today, we will begin the final revision phase of our directional antenna project. Last week, two teams tied with equivalent dB gain readings on our test receiver router, but only one can win! 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) and the winner will be the one who sustains the highest (negative) dB reading and signal quality over the longest distance.
We will conduct final tests the week of February 21st (Monday the 20th is a holiday!). To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field). If your team is not present for the final test or you do not have a working antenna to test on Tuesday, February 21st, you will receive a zero on the second half of this project without the opportunity for make-up. (We’re only going out to the field once.)
Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest gain signal over the longest distance will receive a personal pizza and wings party, to be held while everyone else writes a four paragraph personal reflection 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.

All tools and equipment are located in Room 212. The wireless network cards are located in the cabinet closest to the Teacher Workroom door in Room 212. If the cabinet is locked, see Mr. Herrera for the key. If you have not already, you should request a wireless network card and install it in your PC. There should be enough wireless network cards to install one in each team’s PC for testing.
Please use this time to make progress on your project. I have extended the time well beyond the original projected testing date, but we do not have unlimited time. On Tuesday, March 1st, we will go out to the football field and test all completed antennas to allow those with working products to see the results and modify their designs if necessary. It is in your best interest to test tomorrow so you can tweak the design if necessary before the final test!
We will conduct final tests the week of March 7th. To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field).
