Abstract :
This paper discusses a design of Radial Line Slot Antenna (RLSA) having non-uniform aperture illumination for specific applications. We control the slot couplings to produce a linear taper amplitude distribution that can be applied into two cases: RLSAs having lossy dielectric waveguides and RLSAs for short-range communications. At 60GHz, several prototypes were designed and fabricated, and their measured taper amplitudes give better performances than the uniform designs, from the system point of view.
