ABSTRACT:
An orthogonal polarization duplex send-receive microwave head comprising an elongate housing (10) provided at one end (26) with a longitudinal bore (25) forming a first waveguide and with a transverse bore (28) forming a second waveguide opening out into the first waveguide, and an antenna (44) which extends into the first waveguide, said microwave head being characterized in that said antenna (44) is a receive antenna which extends into said first waveguide at a location situated between the inside end of said first waveguide (25) and the location at which said second waveguide (28) opens out therein, and in that a transmit antenna (45) extends into the second waveguide at its free end, with said antennas being connected to respective coaxial accesses (41, 42) and with a metal plate (31) being disposed longitudinally in the first waveguide between two tranverse planes containing the two antennas (44, 45).
