In this paper, we address the issue of temperature uniformity in high-power antenna systems by proposing and analyzing various design strategies. Specifically, when there is significant spatial freedom in the internal coolant pathways of the cooling plate, a counterflow approach is implemented to achieve temperature uniformity. Conversely, in scenarios where spatial constraints exist, a differential fin area design is proposed to effectively manage heat distribution. Additionally, in cases where the design of coolant pathways is restricted and fin design is not feasible, we suggest minimizing temperature variations by adjusting the thermal conductivity of the carriers located beneath the heat-generating components. This comprehensive approach aims to enhance the thermal management of high-power antenna systems, ensuring improved system stability and performance.
