Abstract
Examples disclosed herein relate to a dual edge-fed Slotted Waveguide Antenna (SWA). The SWA has a plurality of antenna sections having a plurality of radiating slots and configured to radiate one or more transmission signals through the plurality of radiating slots, in which the plurality of antenna sections are symmetric about a termination region between the plurality of antenna sections. The SWA also has a plurality of distributed feed networks coupled to the plurality of antenna sections and configured to serve as a feed to the plurality of antenna sections, in which each of the plurality of distributed feed networks is a corporate feed structure comprising a plurality of transmission lines and further configured to propagate the one or more transmission signals through the plurality of transmission lines. Other examples disclosed herein relate to a radar system for use in an autonomous driving vehicle.
