Determining direction of arrival of an electromagnetic wave

Abstract:

A system for direction of arrival determination includes a waveform detector and processing circuitry. The waveform detector includes a first pair of dielectric structures and a second pair of dielectric structures. The processing circuitry is configured to determine a direction of arrival of an electromagnetic wave incident on the waveform detector. The direction of arrival is determined based on relative power levels in the first pair of dielectric structures responsive to the electromagnetic wave and based on relative power levels in the second pair of dielectric structures responsive to the electromagnetic wave.
