Abstract :
In this paper, a novel approach of linear retro-directive antenna array using 90deg hybrids is proposed. Three-element and four-element passive retro-directive array with experimental results are presented. The measured patterns demonstrate that the main beam is aligned with the incident angle. This approach can be implemented as an arbitrary odd-number and even-number linear retro-directive antenna array
