[0002] Dielectric antenna is a type of antenna, which mainly consists of two types: dielectric resonator antenna (DRA) and dielectric rod antenna. Dielectric antenna is generally made of low-loss high-frequency dielectric material (such as polystyrene), with simple structure, low cost, light weight and reliable performance. Stepped dielectric antenna is a special antenna design, which is usually used in radar systems and mobile communication systems. The design of this antenna is based on high-order mode superposition to achieve wide beam coverage.

The structure is compact, which not only reduces the overall size of the combined antenna and realizes the miniaturized design of the combined antenna. However, the combined antenna is disc-shaped, the space utilization rate is low during installation, and the bottom is closed and the heat dissipation effect is poor. Utility Model Content
