Hi. I wonder, if PCB have trace-antenna , and pcb RF output is 433mhz, it is very important smd components footprint shape , if they are connected to antenna? Thanks !
Yes. For a reliable 433 MHz design:
1. It is important to use SMD devices.
2. The trace lengths, widths, thicknesses, and shapes all are very important.
This is what i mean. This is board with trace-antenna (please see attached picture) . SMD parts, that are connected straight to the antenna have rounded footprints. This is because of high frequency radio waves reflections ?
