Traveling-Wave Fed Dielectric Rod Antenna for 3D Scanning MIMO Sensor

Designed multiple-input and multiple-output (MIMO) millimeter-wave (mmWave) sensor antennas, enabling beamshaping and beam tilting for uniform indoor area coverage. Guidelines and design steps are provided for traveling-wave fed dielectric rod antennas with beam tilting up to 50° in elevation plane, peak gain 9 dBi and efficiency of better than −1.5 dB at frequency band 57 –65 GHz. Described low-profile flush-mounted MIMO mmWave sensor antenna design and topology is visually appealing for the indoor installations. Featuring phase error of less than 15°, with 10° on average within the field of view enables accurate object positioning and trajectory tracking; functional area customization, precise subdivision of spaces and scenes and artificial intelligence super-sensing recognition.
