Abstract
A radar level gauge using electromagnetic signals is provided, which includes a connection arrangement for connecting a transmitter receiver circuit board and an antenna unit with one another, with which the horizontal size of the radar level gauge may be reduced and reflection and transmission losses may be suppressed as well. The transmitter receiver circuit board 32 is so disposed in a housing 12 as to extend vertically. The connection arrangement includes a waveguide sequence which is fed at a feed terminal 32a formed on the transmitter receiver circuit board 32 and composed of three waveguides W1 to W3. Specifically, the waveguide sequence includes, in sequential order from the transmitter receiver circuit board to the antenna unit: a circular waveguide W1 extending horizontally and perpendicular to the transmitter receiver circuit board; a rectangular waveguide W2 in connection with the circular waveguide W1 and extending vertically; and a second circular waveguide W3 further in connection with the rectangular wave guide W2 and extending vertically.
