  • Waveguide receiving antenna
    Patent number: 4177467
    Abstract: An antenna for the short-range reception of an emitted signal comprises at least two independent sectors for the coarse location of an emission-beam source in two predetermined directions. Each sector is constituted by a waveguide having a single open face oriented in the intended direction of surveillance. A microwave diode is placed within each sector at right angles to, and at the geometrical center of, the supporting wall of the waveguide which is associated with the diode. The frequencies detected by the antenna are within the range of 10.sup.9 Hz to 30.times.10.sup.9 Hz.
