As an important part of millimeter wave radar, the design and material selection of millimeter wave sensor housing are crucial to the performance and durability of the radar. The following is a detailed analysis of the millimeter wave sensor housing:

1. Function and effect

The millimeter wave sensor housing mainly plays the following roles:

1. Protect internal components: The housing can protect the sensitive components inside the millimeter-wave radar, such as the antenna, RF front end, etc., from damage by the external environment, such as dust, moisture, impact, etc.
2. Electromagnetic shielding: The shell material must have electromagnetic shielding function to reduce the impact of external electromagnetic interference on radar performance.
3. Heat dissipation and heat insulation: The shell design needs to consider heat dissipation performance to ensure that the radar can operate stably under high load. At the same time, the shell must also have a certain heat insulation performance to prevent internal components from overheating.

2. Design and Materials

1. Design requirements:
- Compactness: To fit into the tight spaces of devices such as cars, the housing design needs to be as small as possible.
- Lightweight: Reduce overall weight, energy consumption and costs.
- Easy to install and maintain: The casing should be designed to be easy to install and disassemble, and to facilitate subsequent maintenance.

2. Material selection:
- Radar radome: The material needs to have low dielectric constant, low dielectric loss, low warpage, laser welding and chemical resistance. Optional materials include PBT, copolymer PC, PPO, PEI, etc.
- Back cover (bottom plate): The material needs to achieve EMI electromagnetic shielding and thermal conductivity, low warpage, laser welding and laser marking, and chemical resistance. Optional materials include PC/PBT, PA, PPS, PPO/PPA, etc.
- Microwave absorbing materials: used to absorb electromagnetic noise near the antenna and improve the radar signal-to-noise ratio. Optional materials include PBT, PC, PEI, etc., and their absorption rate and operating temperature and other conditions need to be considered.

3. Welding method

Laser welding is usually used for the welding of millimeter-wave radar housings. Taking PBT material as an example, the use of high-penetration PBT material is the best way to solve the problem of surface burns during welding. At the same time, the use of specially designed fixtures and good laser plastic welding equipment can also reduce the possibility of burns. In addition, welding process monitoring and quality monitoring are also key to ensuring welding quality.

IV. Conclusion

As an important part of millimeter wave radar, the design and material selection of the millimeter wave sensor housing have a significant impact on the performance and durability of the radar. When designing and selecting the housing, factors such as its functional requirements, material properties, and welding methods must be fully considered to ensure stable operation and long-term use of the radar.
