摘要：
A holographic-inspired one-dimensional leaky wave antenna is proposed, which is capable to control independently multiple radiated beams with a single feed. Contrary to previous implementations, where multiple feeds were used for the excitation of an equal number of beams, or where a metasurface was divided into sectors, each one controlling a different beam, here we offer a reconfigurable single-source metasurface antenna designed with superposition of each individual beam modulation. The unit cell of the proposed antenna is tuned with a low-loss Schottky diode for operation at millimeter-wave frequencies. Simulated results for the novel multiple beam antenna verify the theoretical analysis, and exhibit an independent beam steering at 85 GHz.
