In this study, the thermal management problem of the modern communication systems with small array sizes is addressed. A novel dual-functional active antenna design strategy is introduced for adjustable frequency of operation and cooling extension at millimeter-wave bands. The concept is based on placing different types of heatsinks on the same...

The thermal and electromagnetic effects of varying the ground plane thickness and aperture size of the 5G integrated base station antennas are investigated. A double-sided PCB structure is designed with antennas and digital beamforming chips on the opposite sides. Fully-passive cooling is achieved by using fanless CPU coolers attached to the...

The challenge of cooling in mm-wave chipintegrated base station antenna arrays is addressed. Several approaches in thermal modeling of electronics are revisited and discussed. The two-resistor compact thermal model is applied to predict the junction temperatures of the beamformer chips. Thermal simulations are performed for two fabricated arrays...
