Compact lens antenna

A compact lens antenna comprises a lens medium body provided with a feed source cavity and a feed source at least partially arranged in the feed source cavity. The lens medium body comprises a plurality of nested bodies which are nested together; and the lens medium body is arranged to realize electromagnetic wave phase compensation and optimize antenna performance by adjusting the sizes, the thicknesses and the medium materials of the plurality of nested bodies. The compact lens antenna is smaller in size, lighter in weight and reduced in wind resistance, and the installation reliability and the installation convenience of the compact lens antenna on an iron tower are improved. In addition, by changing the shape of the lens medium body, increasing the compensation medium or increasing the dielectric constant and the like, the phase of electromagnetic waves is compensated, and the performance of the antenna is optimized. 一种紧凑型透镜天线，包括：其上开设馈源腔的透镜介质体及至少局部设置在馈源腔内的馈源；透镜介质体包括多个互相嵌套在一起的嵌套体；透镜介质体设置成通过调整多个嵌套体的尺寸、厚度及介质
