Building a Directional Tin Can Antenna
In Antenna Cble category, you learned how to make a Wi-Fi antenna cable that can be used to connect an external antenna to your Wi-Fi card or access point. It is now time to build an antenna and put the …
Where to Drill
We will be using a copper wedge as the driven element or radiator. The location and length of this element is extremely important. Although we will not be going too deep into the math here, it’s important to understand where …
Fitting the Radiating Element
One of the most important parts of the antenna is the radiating element.While different shapes will change the way the antenna works, its signal strength, and its efficiency, it is not super critical if you do not get it bang …
Final Construction and Weatherizing
This is the final stage of the coffee can antenna project.Time to put it all together!
Step 1: Building the N-Connector
Putting this together is fairly straightforward. The radiating element should fit inside the opening of the N-Connector. This might …
Extra: Antenna Simulation and Patterns
There is some free antenna simulation software available on the Web called 4NEC2. The basis of the simulation is the “Numerical Electromagnetic Code,” hence NEC. This software can be used to simulate thousands of different antennas. One such antenna is …
