What size are Radar/Antenna substrate?

The size of the radar and antenna substrate is a critical consideration during the design and manufacturing process. The dimensions of these substrates often vary based on the needs of the specific application. From tiny antennas to large radar systems, substrates of all sizes play key roles in different applications.

For micro-antennas and small radar systems, the size of the substrate is usually smaller. This small size facilitates integration into compact devices such as smartphones, automotive radars, and wearables. In these applications, the substrate needs to be flexible and compact enough to fit within the device’s space constraints and provide stable signal transmission and performance.

For large radar systems, the size of the substrate may be larger. These systems are often used in military, aerospace, meteorological and other fields and need to handle larger amounts of data and longer-distance signal transmission. Large substrates accommodate more circuit components and connectors and provide more space to optimize signal transmission and thermal management.

In addition to differences in size, the shape of the radar and antenna substrates also varies depending on the specific application. Some applications may require long or shaped substrates to accommodate specific installation environments or signal coverage requirements. Other applications may focus more on the compactness and regular shape of the substrate to facilitate manufacturing and integration.

In short, the size of the radar and antenna substrate is the result of a comprehensive consideration, which needs to balance factors such as the space constraints of the device, signal transmission requirements, thermal management requirements, and manufacturing costs. Careful design and selection of appropriate materials ensure optimal performance and reliability of the substrate in a variety of applications.
