We're designing new linearly-polarized cylindrical patch antennas for:
- 5.675 GHz (802.11a, telemetry)
- 2.390 GHz (amateur TV)
- 1.575 GHz (GPS)
Although we're calling them CPA v4, they are almost exactly similar to the v3 design - just tweaked here and there. Our old design notes can be found here, and the construction notes can be found here.
Here is the v4 design file: cpa v4 calculator.xls
To use the file, simply:
- Copy the green section
- Paste it into a file or text editor.
- Replace all tabs with spaces.
- Copy the new text.
- Open a new board layout in EAGLE.
- Right-click in the command line editor in EAGLE and choose 'Paste'.
- Hit 'Enter', and the CPA should magically assemble itself in EAGLE.
TODO: Add more about materials, who we're using to fab, etc etc.
