An Experimental Study on DOA / DOD Measurement Method at 300 GHz Band by Double-Directional Rotating Reflector Antenna
Designing antennas for 300 GHz band use requires the construction of a propagation model. To achieve this, it is important to grasp the DOA (Direction of Arrival)/ DOD (Direction of Departure) characteristics. We have developed a rotating reflector antenna that can mechanically perform azimuthal beam scanning to enable DOA/DOD measurement in the 300 GHz band. In this report, we propose a DOA/ DOD measurement method that uses the rotating reflector antenna as both the transmitter antenna (Tx) and the receiver antenna (Rx). In addition, experiments using our measurement method were conducted in a shielded room in a multi-reflection environment, and its effectiveness was confirmed by comparison with ray-trace simulating.
