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. Study of and design procedure for dual circularly polarized ... This dissertation, “A Study of and Design Procedure for Dual Circularly Polarized Waveguide Slot Arrays,” is hereby approved in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY in the field of Electrical and Computer Engineering. DEPARTMENT or PROGRAM: Electrical and Computer Engineering Signatures: Parallel-Plate Slot Array Antenna for Deployable SAR Antenna ... Parallel-plate slot array antenna fed by rectangular waveguides at its lower-edge sides has been proposed. This antenna panel can be applied for dual circularly polarized deployable synthetic aperture radar (SAR) antenna onboard small satellite. Broadband waveguide slot array for SAR - Electronics Letters ... A new kind of wideband waveguide slot array for synthetic aperture radar (SAR) is presented. Elliptical slots are first used for designing the waveguide slot antenna. An eight-element waveguide slot array operating at X-band is designed and measured. Predicted results are compared with measured data and good agreement is reported.
