AntWave: Antenna & RF Toolkit

rf.microwave.lab

About this app

AntWave is a professional mobile computing suite developed by a senior phased-array antenna engineer. It is designed to provide convenient and efficient analysis for antenna design, microwave systems, and RF engineering.

The app transforms electromagnetic theories into intuitive engineering results, with all algorithms based on the International System of Units (SI) and high-precision physical constants. With more than 20 core modules, the application covers basic antenna and microwave calculations, transmission line impedance, and antenna metric calculations.
