I have designed a simple PCB with the follow layers
- Top Layer, high speed traces (rest ground copper)
- Inner 1, Ground Copper area everywhere apart on the very left side where the trace antenna will be places and appart from the vias between bottom and top, however no traces on this layer
- Inner 2, Power lines only (5V, 3.3V, 4V)
- Bottom Layer, some low speed traces and some vias for the high speed traces go on bottom layer in order to facilitate their tracing. (rest ground copper)
The trace antennas I see are usually top and bottom layer but since the antenna is high speed, shall I only use the traces of it only on the top layer? On the following picture you can see the antenna, Red is the Top and Blue the bottom layer. Can I leave it like this or I should turn everything red?
Are there any comments/recommendations for the layering that I did(high speed top, low speed bottom and few vias for the high speeds on bottom aswel?
