Hi,
I have to measure S11 mag for some PCB antennas, in GSM bands and also in 2,5GHz. The connector I use is U.FL from Hirose. For the test port I use an N-SMA adapter, then a SMA-U.FL adapter, then a coax with U.FL plugs at both ends. How can I calibrate the reference plane at the end of the U.FL receptacle which is connected directly to the antennas on the PCB? I do not require high precision results, any more or less precise calibration method would be fine. The VNA is an Advantest R3765BH.
