Measured on a real VNA.
Not a promise, a measurement.

We measured 43 structures on a calibrated LiteVNA64. The 9 shown here, the most representative across antennas and filters, are compared, point by point, against RayRF. Frequency match is the headline. Per-plot magnitude offsets are shown alongside, but we do not claim a headline magnitude number: at sharp resonances a small frequency shift translates into a much larger magnitude shift, so a single per-cent figure would not be honest.

Worst-case frequency error across every dip on every structure shown here.

Measured

43structures

43 structures measured on the VNA. The 9 shown here, eight patch antennas plus an interdigital bandpass filter, are the most representative. All on ZYF 300CA-C, a 0.76 mm PTFE substrate, Dk 2.94, Df 0.0016.

How the measurements were taken.

Instrument

LiteVNA64. Warmed up for 24 hours before measurement, so the instrument is at thermal equilibrium when sweeps begin.

Calibration

SOLT with quality standards, repeated 5 times at equal time increments over the 10-hour session to bound drift.

Sweep

12,276 points per DUT from 1 MHz to 8 GHz, with 5-trace averaging.

S₁₁

Reflection measured with a precision 50 ohm load terminating the through port, to suppress false reflections from cable mismatches.

S₂₁

Transmission via the VNA's direct through-measurement. No de-embedding, so the published number is what you would measure on your own bench.

Range note

LiteVNA64 is rated to 6.3 GHz. Content past that is shaded reference only on every plot. With 5-trace averaging it is still useful, just noisier.

Per-DUT comparison

One row per structure. Hover the plot for exact values, double-click to reset zoom. Toggle dB / linear, and on multi-port DUTs switch between S11 and S21. The dip cards under each plot show the frequency offset and magnitude offset between the simulated and measured resonances.

[IDF01]Interdigital Bandpass Filter (~2.4 GHz)

Four-pole interdigital bandpass filter on ZYF 300CA-C (PTFE, Dk 2.94). The full band shape (number, spacing, and ordering of all four S11 reflection poles) is captured. Pole frequencies match within 1% across the band.
