A linearly polarized radial-line slot-array antenna with a broadened beam
Bialkowski, M. E. and Davis, P. W. (2000) A linearly polarized radial-line slot-array antenna with a broadened beam. Microwave and Optical Technology Letters, 272: 98-101.
The beam shaping of a linearly polarized radial-line slot-array (LP RLSA) antenna is demonstrated with the production of a prototype with a broadened main beam pointed in an arbitrary direction. The method of synthesis is presented, which utilizes a simple but accurate radiation model for the RLSA antenna to predict radiation characteristics. Experimental results for a Ku-band LP RLSA antenna manufactured using the described techniques show good agreement with the theoretically predicted performance. (C) 2000 John Wiley & Sons, Inc.
