Figure 7-3. Babinet’s Principle | Waveguide Slot Antenna… Waveguide slot antennas are often used as omnidirectional microwave antennas. According to Watson4, the slot array was invented in 1943 at McGill University in Montreal. Unique features of these antennas are horizontal polarization and omnidirectional gain around the azimuth. Novel slot pattern in bifurcated waveguide for … abstract = "Slot radiators in polarization-selective dual-mode waveguide arrays present an unusual analytical problem since the radiating apertures may be three dimensional. This is the case when a typical slot in the broad wall is shunted by some kind of clearance notch in the centre wall of a... The graduate school of natural and applied sciences For horizontal polarization a novel, non-inclined slot is proposed and used to achieve highthe polarization of electromagnetic waves transmitted and/or received by the system.Finally, waveguide rows which are used in the dual polarized antenna for horizontal polarization are...
