Waveguide slot array antenna design

Mar 28, 2016 · Slotted waveguide arrays consist of a number of slots cut into the walls of a waveguide forming an array with the slots acting as individual radiating elements. The specific design task here is a 10-element transversal slot array cut into the upper wide side of a WR-51 standard rectangular waveguide. The design of waveguide-fed slot arrays - ResearchGate

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 ...

A cavity-backed coplanar waveguide slot antenna array A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. ex W1GHZAntenna Book W1GHZAntenna … 7.2.3 Waveguide slot array design A sketch of a waveguide slot antenna with the pertinent dimensions is shown in Figure 7-5. The first design consideration is that the slots be resonant so that they provide a resistive load to the (waveguide) transmission line. Non-Resonant Slotted Waveguide Antenna Design Method ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od.
