| contents | We present experimental validation results of a pulse-width-dependent antenna based on a waveform-selective metasurface that behaves differently according to the incoming waveform, more specifically, the incoming pulse width, even at a fixed frequency. This waveform-selective behavior is integrated with an antenna design to preferentially accept a predetermined incoming waveform while rejecting another waveform at the same frequency. In particular, we report how the waveform-selective antenna performance can be evaluated for diverse incident angles, which is enabled by a measurement method based on a reverberation chamber. This method facilitates variation of the electromagnetic fields and modes inside the chamber and mimicking of complicated wireless communication environments through rotation of the internal stirrer. The experimental results verify that our antenna design concept based on waveform-selective metasurfaces can filter different signals with a wide range of incident angles, opening the door to utilizing such pulse-width-dependent antennas to suppress electromagnetic noise in more realistic wireless communication environments. |
