019 Inverted-F PCB Antenna: How to tune PCB circuits using a NanoVNA
Published at : 23 Dec 2025
PCB antennas are pretty common because they are small and cheap. Can we use them for our projects? How do they work? And: How can we test and tune them? Let’s look at an antenna for the 868-915MHz ISM bands. As a side-effect, you will learn how to measure impedances directly on a PCB.
