Dual Antenna Array System for Wide and Narrow Beam Coverage

The system uses two dedicated antenna arrays instead of one multi-functional array. The first array with larger spacing optimizes wide beam performance, while the second array with smaller spacing optimizes narrow beam performance. This segmentation improves beam coverage performance for both beam types compared to a single array, while the overall system complexity remains manageable through standardized array designs.

Both antenna arrays are designed with the same basic structure and can support multiple frequency bands through multi-band combiners, providing universal functionality. This allows the system to maintain relatively simple device complexity while achieving specialized beam coverage performance through the dual-array configuration.

The system segments the beam formation function into two arrays: the second antenna array with smaller column intervals is optimized for narrow beam quality, while the first antenna array with larger column intervals is optimized for wide beam coverage capability. This segmentation resolves the contradiction by assigning different spatial configurations to different beam requirements.

The system adds a dimensional aspect by using two arrays with different column interval characteristics working in parallel. Instead of trying to optimize a single array for both narrow and wide beams, the solution operates in a higher-dimensional space where each array contributes its specialized capability, achieving both narrow beam quality and wide beam coverage through combined operation.
