Waveguide Slot Array Design

This is the first comprehensive treatment of slotted waveguide array antennas from an engineering perspective. It provides readers with a thorough foundation in applicable theories as well as hands-on instruction for practical analysis and design of important types of waveguide slot arrays.'Slotted Waveguide Array Antennas' goes beyond some of the commonly discussed topics and ventures into areas that include: higher order mode coupling and edge effects; performance optimization in terms of bandwidth and pattern performance; special slot excitation methods; applications such as monopulse and phase steering; and manufacturing tolerances.With specific examples of waveguide array designs accompanied by detailed illustrations and antenna characteristics and many applications, this is a must-have reference for engineers involved in the design and development of slotted waveguide arrays. Additional value is provided by a thorough overview of the related literature in the field and the introductory chapters include the history of these antennas.

Slot Array Antenna Design

Tests of the theory include the resonant length of a zero offset slot, resonant conductance versus offset and resonant conductance versus frequency for a single slot, and self- and mutual admittances for two staggered slots. The design and performance of a two-by-four longitudinal shunt slot array is also described. And slot offset parameter to be determined with the specification of desired pattern and input admittance. Representation of the active admittance in terms of voltage, self and mutual admittance of the slot is presented. A similar design approach is developed for series slot array that are waveguide-fed 2 and broad wall slots that. Any account of antenna arrays must be preceded by describing the effects of mutual coupling between radiators. This is as true for microstrip arrays as for any other type of antenna array. To optimize and characterize an array element in isolation and to use the information to design an array antenna usually ends in disappointment. This paper discusses the design, analysis, and development of waveguide-fed planar slot arrays to achieve low-average-sidelobe specifications, as may arise in radiometer applications. Such antennas may be required to meet strict average sidelobe levels in different angular regions, and low average return loss over a specified bandwidth.
