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.
An integrated function microwave radiating structure capable of radiating electromagnetic energy at several selectively predetermined different frequency bands simultaneously and which can be used as an element of a large microwave array … US5475394A - Waveguide transition for flat plate antenna… In a flat plate antenna, insertion loss is reduced significantly by providing an extensive waveguide structure at the back of the ground plane of the antenna. Depending on antenna size, the waveguide may feed the antenna at one or a … High-Gain Millimeter-Wave Planar Array Antennas with Traveling… The slotted waveguide planar antenna is composed of one feeding waveguide and two or 24 radiating waveguides. Spacing of slots in x-direction is one guided wavelength of the radiating waveguide.

The losses of the radiating waveguide are reduced from 3.7 to 0.45 dB. Experimentally, the gain was shown to increase 5.5 dB.Further, the problem arises because the large dielectric constant of LTCC course a large long-line effect making the bandwidth narrower in a series-fed array antenna. Radiation From Tilted Rectangular Waveguide Slot … The simplest rectangular waveguide slot antenna is a hollow rectangular waveguide that has several slots on the wall. There is a rich literature on design and analysis of traditional arrange-ments [1]–[6]. In this paper, we introduce the tilted rectangular waveguide slot antenna (Fig. Keywords: antenna, slotted, array, rectangular waveguide… Abstract: Slotted linear antenna array at Ku band for radar application is designed with design of waveguide with standard waveguide dimensions at Ku bandrespect to the board side of the broad wall of the rectangular waveguide at Ku band. Single slot need to be designed and optimized for. An Annular Waveguide Slot Antenna CIRCULAR boundary rectangular waveguide slot array an-tennas have been the major solution in many communica-tion head unit antennas. Low profile, ability for different cur-rent distribution implementation, and ease of boundary forma-tion are among the advantages of such antennas.
