There has been a general trend of radio and sensing applications shifting to higher frequencies, either to avoid interference due to the growing use of RF and microwave spectrum or to take advantage of the growing accessibility of millimeter-wave hardware. This is true for consumer, industrial, military, aerospace, and satellite communications applications alike. Regardless of ..

Though the terms single-input single-output (SISO) and multi-input multi-output (MIMO) originate with controls engineering, SISO and MIMO are now very commonly discussed in reference to RF antennas. In controls engineering, a SISO system has only one input and one output, such as a DUT with only 2-ports that you can measure with a 2-port Vector ..
