Ultra-wide angle radar system

Abstract

An ultra-wide angle radar system includes a first antenna module, a second antenna module, and a third antenna module. The first antenna module has a flexible board antenna or an integrated circuit board. One side of the second antenna module is adjacent to one side of the first antenna module and one side of the third antenna module is adjacent to another side of the first antenna module. The first, second, and third antenna modules have distinct radiating directions. One or both of the second antenna module and the third antenna module, connected to the first antenna module, transmit signals by coupling radiation or metallic connections. Therefore, the viewable angle during detection is greater than 180 degrees. The design can be adjusted according to requirements for different detection ranges in different applications such as long-range, medium-range, and short-range detection.
