Important results from the project
The goals were met through the development of tools to optimize the division of antenna elements, ensuring a smooth and energy-efficient power distribution. The project contributed insights into how the design of the feed networks affects antenna characteristics, resulting in recommendations for optimal division. One of the resulting publications is

Expected long term effects
Antenna arrays are becoming increasingly important for future communication and sensor systems, where the need for improved signal handling and spectrum utilization is driving development. In the long term, fully digital arrays are expected, but until then, subarray division is a key technology. For high-performance products, this is a transitional solution, while for cost-effective systems it remains relevant and enables advanced sensors in simpler products.
Approach and implementation
The project was carried out as a collaborative project between Saab, Ericsson and KTH. The research has been conducted at KTH, where Saab and Ericsson have provided input as industry representatives. During the project, we have had monthly project meetings via Teams, where the focus has been on the simulation process. KTH has presented simulation results, and the industry partners, Saab and Ericsson, have provided input and feedback on these.
