Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna array connectivity layouts in millimeter-wave RF systems are inefficient due to large signal distribution networks that occupy significant space, result in signal losses, and limit the number of active antennas that can be connected, complicating design constraints of size, power consumption, and cost.
Innovation Solution
A novel layout design featuring triangular antenna edge blocks arranged within a rectangular layout with a star-like signal distribution network, reducing the number of splitter elements and signal routing, allowing for more active antennas to be connected within a smaller space while minimizing signal losses.

1Area of stationary object
If conventional antenna array connectivity layouts are used, then signal distribution can be achieved, but the signal distribution network occupies significant space and results in signal losses
Solution Approach 1:
The signal distribution network is segmented into multiple triangular sub-networks, each serving a specific antenna edge block. This segmentation reduces the overall routing distance and number of splitter elements required, thereby reducing signal loss and occupying less space on the PCB.
Solution Approach 2:
The patent transitions from conventional rectangular or linear signal distribution topologies to a triangular geometric arrangement. This dimensional change optimizes signal routing paths and reduces the area occupied by the distribution network while minimizing signal attenuation through shorter connection lengths.
2Adaptability or versatility
If conventional layouts are used, then connectivity is provided, but the number of active antennas that can be connected is limited
Solution Approach 1:
The antenna array is divided into multiple edge blocks, each connected to the signal distribution network through optimized triangular routing. This segmentation allows more antenna elements to be connected within the same PCB area by reducing the space required per antenna connection.
Solution Approach 2:
The triangular layout arrangement allows for more efficient packing of antenna elements and their corresponding signal routing paths. This geometric optimization increases the density of connectable antennas within the available PCB area compared to conventional layouts.
3Adaptability or versatility
If more active antennas are connected, then connectivity increases, but design constraints of size and power consumption are complicated
Solution Approach 1:
The signal distribution network is organized into modular triangular units that can be systematically replicated and scaled. This modular segmentation simplifies the design process for accommodating more antennas, as the same triangular pattern can be reused with minimal design changes, reducing overall design complexity.
