- Abstract
- This paper introduces a multiple beamforming method using the principle of superposition. Using the principle of superposition, it is possible not only to form multiple beams very simply, but also to suppress side lobes or to separate two adjacent beams. In this paper, the realization of those mentioned above using the principle of superposition is explained using an array factor theory, and a dual beam transmitarray antenna with a superstrate consisting of unit cells arranged in 11x11 is designed using the principle of superposition. The gains of antenna was simulated to be 14.22 dBic and 15.64 dBic at in=0o and 18 0 when k20o. © 2018 KIEES.
