WAVEGUIDE SLOT ARRAY DESIGN Technical Memorandum No. 348 by Ivan P. Kaminow" and Robert J. Stegen 1 July 1954 This technical memorandum constitutes partial fulfillment of the work under Contract AFJ9(604)-26Z, Change C. IThe Government has the right'to reproduce, use and disclose this Antennas: The Slotted Waveguide Antenna An example of a slotted waveguide array is shown in Figure 1 (dimensions given by length a and width b) Figure 1. Basic geometry of a slotted waveguide antenna. As in the cavity-backed slot antenna, each slot could be independently fed with a voltage source across the slot. However, (especially for large arrays) this would be very difficult to ... Antennas: The Slotted Waveguide Antenna The waveguide itself acts as a transmission line, and the slots in the waveguide can be viewed as parallel (shunt) admittances. The end of the waveguide is short circuited, so a rough circuit model of Figure 1 is: Figure 2. Circuit model of slotted waveguide antenna. The last slot is a distance d from the end (which is short-circuited, as seen ... Radar Basics - Slot Antennas Slot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. But also older large phased array antennas used the principle because the slot radiators are a very inexpensive way for frequency scanning ...

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. In order to confirm the usefulness of this method, a non-resonant waveguide array antenna with longitudinal slots cut in a broad Design of a new waveguide slotted antenna array - e-fermat.org
Investigation and Design of a Slotted Waveguide Antenna ... Investigation and Design of a Slotted Waveguide Antenna with Low 3D Sidelobes by Andries Johannes Nicolaas Maritz Thesis presented in partial fulfilment of the ex W1GHZAntenna Book W1GHZAntenna BookW1GHZAntenna Book ... 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. PARAMETRIC STUDY OF WAVEGUIDE SLOTS AND ANALYSIS OF ... 2. SYNTHESIS OF A LINEAR ARRAY ANTENNA Design of a linear array antenna incorporating waveguide longitudinal slots as radiators is described. Prior to the design of an array it is required to determine the resonant slot length, equivalent circuit and variation of the circuit parameters with the change in offset value. Antennas: The Slotted Waveguide Antenna (Planar Array of ...
