Abstract
The sidelobe level of an array antenna fed by a Rotman lens can be reduced if pairs of adjacent beam ports are combined, and the system is fed through these summing ports. This procedure does not reduce the overall antenna gain. The conditions for this operational mode are explained, and the results are given.
