An efficient design of a 3-D printed dielectric dome array (DDA) antenna featuring ultrawide-angle beam scanning is presented in this article. Instead of using optimization tools, the inner and outer contours of the dielectric dome lens (DDL) are determined by the derived phase distribution <inli...
