چکیده

Slotted waveguide antennas (SWA) are often employed in radar applications where design specifications commonly require high gains and mechanical robustness. Since the peak power transmitted by radar antennas is usually very high, waveguide antennas present a practical alternative to planar arrays. While numerous design references and guidelines exist for planar arrays, there are far fewer for slotted waveguide antennas. This article presents a comprehensive workflow for the analysis and design of a slotted waveguide antenna with slots placed on the narrow wall of the waveguide. The virtual design is modeled and simulated using two different numerical methods and different mesh types. This simulation is compared to the analytical solution for array antennas and to the performance of a physical prototype.

Antenna Patterns from Single Slots in Carbon Fibre Reinforced Plastic Waveguides

Slotted Waveguide Antenna Stiffened Structure (SWASS) is a type of conformal load-bearing antenna where top-hat cross-section stiffeners on skins, or blade stiffeners in sandwich panels, serve the dual purpose of acting both as structural stiffeners and as waveguides. Cutting slots through the outer skin and into these waveguide stiffeners creates slotted waveguide antenna arrays. Two of the ke...

Measured Performance of Low-Sidelobe Narrow-Wall Slotted Waveguide Planar Antenna in Millimeter-Wave Band

Low sidelobe slotted waveguide antenna is developed in the millimeter-wave band. Millimeter-wave technologies are expected to apply to automotive radars and high-bit-rate mobile communication systems because high gain and narrow beam-width is possible even though the physical size of the antenna aperture is small. Waveguide antenna is advantageous for high gain applications since the feeding lo...

Improving the Thermal Characteristics of Semiconductor Lasers Using a New Asymmetric Waveguide Structure

   Self-heating leads to a temperature rise of the laser diode and limits the output power and efficiency due to increased loss and decreased differential gain. To control device self-heating, it is required to design the laser structure with a low optical loss, while the heat flux must spread out of the device efficiently. In this study, a new asymmetric waveguide design is proposed and th...
