摘要：

A lens array has been developed to reduce the height of the lens and has proven to achieve the same gain as a large single lens antenna with a low antenna profile. However, the amplitude is not completely uniform in the aperture distribution. Therefore, a concave-convex lens shaping is applied to the lens element to improve the lens aperture uniformity. The proposed concave-convex shaped lens array is demonstrated by electromagnetic simulation at 300GHz achieving high gain at 35.6dBi with reliable side-lobe-level (SLL) at -11dB.
