Abstract :
In this paper, we propose and design a coaxial-line fed slot array with a waveguide-to-coaxial transition using a crank-shaped slot. We analyze the 8×8-element trapezoidal array with the designed transition. The bandwidth for VSWR less than 1.5 is 2.1% in the waveguide for boresight radiation and 2.0% in the waveguide for tilted radiation from 77 to 81 GHz.
