This chapter describes the design and development of broadband slotted waveguide array (SWA) antenna. Conventional SWA antenna offers a few percentages of bandwidth, which can be enhanced using proposed novel differential feeding technique which electrically divides large resonating SWA into wideband subarrays by creating virtual shorts. This chapter discusses concepts to achieve broadband ... ANTENNA MAGUS - APP Notes | The leading Antenna Design ... Waveguide slot arrays are typically used at microwave frequencies and are particularly popular for radar applications. They are robust, have low-loss and are able to withstand high powers. These antennas consist of a waveguide with slots cut into the broad side. A WIDEBAND SLOTTED WAVEGUIDE ANTENNA ARRAY FOR ... - jpier.org 3. ANTENNA SYNTHESIS Our design goal was to develop an X-band slotted waveguide antenna with a 4– £ 6– antenna beam and the relative operational bandwidth of about 15%. A rectangular array of radiating slots has been selected. The rectangular aperture is separable one [7], so it is possible to Design of Slotted Waveguide Antenna for Radar Applications ...

A slot antenna's main advantages are its size, design simplicity, and convenient adaptation to mass production using either waveguide or PC board technology. Due to Babinet's principle a slot in a waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot. This can be used to determine the radiation ...
