Microstrip Patch Antenna [Verification by Measurement]

Microstrip patch antennas are among the most popular antennas, used in various application areas. Modelling of such antennas is typically straight forward and can be done in WIPL-D general-purpose 3D modeler WIPL-D Pro. More advanced geometries or geometries provided by CAD file can be made simulation ready in AW Modeler or WIPL-D Pro CAD. A simple microstrip patch antenna is simulated.

The simulation itself is not of much relevance here. Simple printed antennas are simulated in WIPL-D at regular desktop or laptop PC in seconds. The application note was focused to verify the simulated results by using measurements performed by WIPL-D team.

The software predicted the resonance at 1.905 GHz, while measurements pointed to 1.906 GHz. The simulated bandwidth is 19.35 MHz while the measured one is 19.3 MHz. The relative discrepancy is 0.05 % for resonant frequency and 0.25 % for bandwidth.
