Abstract
The structure of a linearly polarized radial line slot antenna (LP-RLSA) for realizing dual beam operation is presented. The beam-tilt mechanism by the shift of feed point is explained. A model antenna with two feed points demonstrated the dual beam operation, and efficiencies of 33 and 45% were realized. This beam-tilt mechanism can be applied to the narrow range beam scanning.<>
