DIY Directional Antennas 2019 – 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:

DIY Antennas Project Final Reflection Form:

Google Classroom

Topics Discussed:

Wireless Networking
802.11 Wi-Fi spec
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!
