Solution Overview
Problem
Conventional reflect arrays face challenges in maintaining high electric field strength and directional gain when designed for multiple incident angles, and their installation is constrained by the need to align precisely with base stations.
Innovation Solution
A reflect array system with alternating first and second elements arranged orthogonally on an XY plane, allowing two independent incidence-reflectance angles, and a deformable design for flexible installation, including fixing parts for easy mounting on various surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reflect array is designed for a single incident angle and reflection angle, then the electric field strength and directional gain are maximized, but the installation position and angle are uniquely determined, making it difficult to install unless base station position is predetermined
Solution Approach 1:
The reflect array is divided into multiple element rows (first element row and second element row) with different orientations. Each element row is designed to reflect waves at different incident angles, allowing the system to handle multiple incident directions simultaneously while maintaining high electric field strength in each direction.
Solution Approach 2:
The reflect array structure is designed to perform multiple functions: it can reflect incident waves at different angles (first incident angle and second incident angle) to different reflection angles simultaneously. This multi-functionality allows the same reflect array to serve multiple base station positions and orientations without requiring precise pre-determination of installation parameters.
2Adaptability or versatility
If the reflect array is designed to reflect waves at multiple incident angles, then installation constraints are relaxed, but the electric field strength in the desired direction is reduced due to energy distribution across multiple directions
Solution Approach 1:
Different element rows are assigned different local qualities (orientations and reflection characteristics). The first element row is optimized for reflecting waves at the first incident angle, while the second element row is optimized for the second incident angle. This local optimization ensures that each element row maintains high electric field strength for its designated function while the overall system provides multi-angle capability.

Function Achieved in This Case
The system maintains high gain and flexibility in reflecting radio waves at multiple angles without reducing electric field strength, enabling easy installation on diverse surfaces and locations, including ceilings, walls, and floors, and supporting wide-range communication.
Implementation Method 1
Reflect array reflectors are sometimes used to solve this problem... the incident wave is reflected well for forward incidence and for reverse incidence with enough electric field strength of the reflected wave

AI summary
Provided is a reflect array that enables reflectance at a plurality of angles of incidence while maintaining a high gain without causing a decrease in the electric field intensity of a reflector plate, and that can simplify the installation of the reflect array. In the reflect array, a plurality of first elements and a plurality of second elements are arranged on XY plane. The first elements are arranged in Y direction to form a first row of elements. The second elements are arranged in Y direction to form a second row of elements. The first element rows and the second element rows are alternately arranged in X direction. The two angles of maximum reflectance are on the same positive or negative side of X-axis.
