Abstract :
The presented MAR technique is a very powerful and economic method to study the radiation problems for discrete Luneburg lens antennas (DLLA) integrated with conformal patch feed. It enables one to highlight with controlled accuracy all the key physical effects such as the patch-cavity and whispering-gallery resonances and the main beam collimation. This technique deals with a full field computation.
