Abstract
The lens antenna array is typically composed of an electromagnetic (EM) lens and has elements in the focal area of the lens in order to achieve its large antenna gain. In this paper, we first analyze the response model of the lens antenna array, and conclude that the model follows the “sinc” function. The lens array is then applied to a MIMO system that allows millimeter-wave input and the use of new path-division multiplexing. On this basis, we model the channel of the system to derive the channel impulse response, which follows the “sinc sinc” function. Finally, the beamforming process is performed at the receiving end to obtain the received signal, and the signal-to-noise ratio expression is analyzed and optimized to obtain the maximum signal-to-noise ratio (SNR) of the system and the system performance is simulated.
