How does a ground plane antenna work?
As the name indicates the antenna ground plane acts as a simulated ground. It is found that for a monopole antenna like a quarter wavelength vertical, the ground acts as a plane to reflect the radio waves so that an image of the top half of the antenna is seen in the Earth.
Why do we use polygons in PCB?
When you look at a real circuit board, you might notice many complex structures on the surface of the board that are connected back to ground or power. These regions are polygons, and they provide a simple way to control the power and ground distribution throughout a complex PCB.
What does Ratsnest mean?
“Rat’s nest” is an English idiom meaning “a place of great clutter or disorder. “
How do you use Ratsnest?
Use the RATSNEST command to calculate and display the surface of the Polygon. Type in the command Line “Ratsnest” or use the Command button. A Polygon which overlaps itself cannot be calculated. An Error Message will appear: “Signal contains an invalid Polygon”.
How do you get rid of copper pour eagle?
To definitively delete the copper pour, since the polygon is attached to the copper pour, delete the polygon. To temporary remove or hide the copper pour, select the RIPUP tool and click on the polygon. It removes the copper pour while keeping the polygon (dotted lines).
What is a ground plane and why is it used?
What is an antenna ground plane? As the name indicates the antenna ground plane acts as a simulated ground. It is found that for a monopole antenna like a quarter wavelength vertical, the ground acts as a plane to reflect the radio waves so that an image of the top half of the antenna is seen in the Earth.
What is Eagle polygon?
In Eagle polygons are used to make big copper areas on a PCB that aren’t necessarily traces. We use them all the time to fill blank space on a PCB with copper connected to ground. Less frequently we use them to make large power traces such as with the ATX Breakout Board.
What is polygon plane PCB?
Planes in Your PCB Layout. Polygons, also known as copper pours or polygon pours, are areas of the PCB that are filled or flooded with copper. This region is poured around existing components and traces, creating a region filled with copper hat has predefined clearance.
What does Airwire mean in Eagle?
It means you’ve made every route required. If ratsnest says you have “N airwires” left to route, double check your board for any floating golden lines and route them up. If you’ve looked all over, and can’t find the suspect airwire, try turning off every layer except 19 Unrouted.
How do I make an eagle ground plane?
An Eagle ground plane is constructed easily by using the “Polygon” tool. The following steps will explain how. Start with a board where you have routed all the signals except ground.
How do I Turn Off the ground plane in Eagle?
If you want to see it again, just click “Ratsnest”. If you don’t want to calculate and show the ground plane when using the “Ratsnest” command, you can turn it off with the command “SET POLYGON_RATSNEST OFF”. For more information on the “Polygon” tool and how to customize your Eagle ground plane, type “HELP POLYGON” in the Eagle command line.
Will Eagle fill in the polygon?
And ta-da we see a ground fill in the printed circuit board. EAGLE will not fill in the POLYGON until you run the RATSNEST command. Step 4. Isolate!
