Design of compelementary ring array antenna

Abstract EN

The objective of work is to find the scale of ring array antenna for localizing field intensity at certain focal point.

The study is interested in comparison between focusing by setting a scale factor of array antenna to cohere (synchronize) waves of electric field when reaching focal point, and focusing by compensating phase differences that was initiated from ray length differences between waves reaching focal point.

Isotropic sources are used for simulation.

These sources are distributed along a circular ring, each ring of array rings is complement with the previous rings, that means it has a phase complement to a complete cycle( ).
