Splet27. okt. 2024 · If you just want it spaced an amount on the internal layers, use the isolate. Also keep in mind that they need to be different ranks, which controls which one gets priority. Larger board wide polygons should be high rank (5, 6), with smaller areas lower ranks (1, 2). Using ranks you can control which one takes priority. Polygon Pouring with … SpletThe antenna consisted of two elements placing at the upper and lower corners of a PCB with a volume of 50×110×0.8 mm2. An area 10×45 mm2 was cut at the corners of the PCB to make rooms for placing the two antenna elements. The two elements were mirror images of each other on the PCB, hence complementing the radiation patterns.
