一种透镜以及天线结构
By designing a lens antenna using stacked dielectric substrates and combining TM and TE surface wave modes, the problem of achieving broadband, dual polarization, and low cost in existing lens antennas is solved. This results in a high-bandwidth dual-polarization and low-cost lens antenna design suitable for mass production.

AI Technical Summary
Technical Problem
Existing lens antenna designs struggle to simultaneously achieve broadband, dual polarization, and low cost, and are also highly complex to manufacture.
Method used
A lens is constructed using stacked dielectric substrates, combining TM and TE surface wave modes, and a dual-polarized radiation beam is excited by a feed antenna. Directional high-gain radiation is achieved through the design of the thickness and radius of the dielectric substrate.
Benefits of technology
A high-bandwidth (9–17 GHz) dual-polarized lens was achieved, reducing cost and complexity, making it suitable for mass production, and exhibiting low reflection and scattering effects.
