Abstract:
A set of probes for a waveguide, said waveguide including a cup-shaped tube portion, a body portion connected to an end of said tube portion, and a circuit board connected to said body portion opposite to said tube portion for receiving and processing signals; said set of probes comprising a first and a second probe printed on one side of said circuit board facing away from said cup-shaped tube portion of said waveguide, such that said first and said second probes are spaced from each other by a predetermined distance and are in two directions perpendicular to each other; said second printed probes being provided on said circuit board at a position corresponding to a guide slot provided on said cup-shaped tube portion, so that said second probe is able to receive electric waves guided into said guide slot; said set of probes being characterized in that said first and said second printed probes are separately located in two substantially rectangular patterns, one of said two rectangular patterns having said first probe located therein being provided below or above a substantially round pattern on said circuit board, and the other said rectangular pattern having said second probe located therein being provided outside and to one lateral side of said round pattern, and both said two rectangular patterns being provided at an edge adjacent to said round pattern with a feed opening.
