Abstract
This paper proposes a waveguide transmitarray antenna system for millimeter-wave near-field identification and sensing applications, and presents preliminary results of numerical simulation. The transmission layer of this antenna is an array of metallic waveguide elements operating in their fundamental mode. The arrangement and positioning of these elements are based on mathematical equations that are derived using path equivalence principle. The transmitarray design allows multi-beam capability to the antenna system by placing multiple feed sources at the focal arc of the antenna. This antenna is suitable for millimeter-wave identification and sensing applications in various fields such as food safety, medical, industrial etc. due to its high focusing ability.
