Advantages of flush mounted FMCW radar level transmitter lens antennas

Advantages of flush mounted lens antennas The advantages of a flush mounted lens antenna are immediately apparent: Lens antennas do not protrude into the tank and thus allow an almost complete filling of the tank. Using horn antennas means that they protrude from mounting nozzles. Lens antennas however can easily be placed on nozzles as shown in the example of a 50mm nozzle in combination with the 40mm lens antenna. A disturbance signal at the nozzle end, as it is usual at 24 GHz, does not occur. Thus, filling is possible up to the lower edge of the nozzle. The combination of a 70 mm lens antenna with an 80 mm nozzle provides, of course, identical good results.
