Antenna System with Phase Switching for Beam Coverage

The antenna system is divided into multiple antenna arrays (first to eighth arrays) arranged in specific patterns. Each array can be independently controlled to generate beams in different directions, thereby achieving wide beam coverage without requiring a complex mechanically steerable structure.

The patent employs phase switching mechanisms that allow the antenna system to dynamically change beam directions and coverage patterns electronically. This dynamic beamforming capability enables the system to adapt to different communication scenarios without mechanical movement, resolving the contradiction between structural simplicity and beam coverage flexibility.

The patent replaces the mechanical driving motor system with an electronic phase switching system. By controlling the phase of radio frequency signals fed to different antenna arrays, the system achieves beam alignment and directional control without any mechanical moving parts, thereby eliminating motors, reducers, and associated complex installation requirements.

The same antenna arrays that provide radiation functions also perform beam alignment and directional control through electronic phase switching. This multi-functionality eliminates the need for separate mechanical alignment mechanisms, reducing both manufacturing cost and installation complexity while maintaining adaptive beam alignment capability.

Instead of using a single large cylindrical radome structure, the patent segments the antenna system into multiple smaller antenna arrays that can be arranged in a compact planar configuration. This segmentation allows the system to achieve similar or better performance with reduced volume.

The patent changes the fundamental operating parameters by using electronic phase switching instead of mechanical rotation or large radome structures. This parameter change enables the system to achieve high gain and proper radiation patterns in a compact form factor, eliminating the need for bulky cylindrical radomes.

The patent uses dynamic phase switching to concentrate radio frequency energy in specific directions, achieving high gain through constructive interference. By dynamically adjusting the phase of signals fed to different antenna arrays, the system can electronically focus beams to achieve high gain without requiring large physical structures or mechanical alignment mechanisms.

The patent combines multiple antenna arrays with controlled phase relationships to achieve beam forming and directional gain. By merging the radiation patterns of multiple arrays through coherent signal combination, the system achieves high antenna gain equivalent to or exceeding that of large cylindrical radomes, but with simpler structure and higher efficiency.
