We present an automatically optimized near-field focusing radial line slot array (RLSA) antenna. The side lobe level and beamwidth of the normal component of the radiated electric field are controlled during the design process. A set theoretic approach is used to derive the RLSA aperture field distribution generating the required near field over a focusing plane at a given distance from the radiating aperture. The position and size of the slots of the RLSA antenna are automatically controlled to synthesize the derived aperture field distribution. The design approach is validated by measurements at 12.5 GHz.

Abstract
We present an automatically optimized near-field focusing radial line slot array (RLSA) antenna. The side lobe level and beamwidth of the normal component of the radiated electric field are controlled during the design process. A set theoretic approach is used to derive the RLSA aperture field distribution generating the required near field over a focusing plane at a given distance from the radiating aperture. The position and size of the slots of the RLSA antenna are automatically controlled to synthesize the derived aperture field distribution. The design approach is validated by measurements at 12.5 GHz.
