Waveguide Antenna 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.
Waveguide Slot Array Antenna Design
Slotted antenna arrays used with waveguides are a popular antenna in navigation, radar and other high-frequency systems. They are simple to fabricate, have low-loss (high antenna efficiency) and radiate linear polarization with low cross-polarization. ABSTRACT This paper presents the design, fabrication, and operation of an edge-wall slotted waveguide array antenna with metal flare for the generation of ultralow side lobes fan-beam radiation. The single traveling wave array antenna consists of 71 radiating elements. If the waveguide slot antenna is designed in this manner, then all of the slots can be viewed as being in parallel. Hence, the input admittance and input impedance for an N element slotted array can be quickly calculated: The input impedance of the waveguide is a function of the slot impedance.
