How do you measure the impedance of your antenna on a small PCB with a small ground plane?
When connecting a VNA to the PCB with a coax "pigtail", the outer ground of the coax affects the ground plane and changes the measured impedance of the antenna. What type of test setup do you use to reduce this effect?
