Des réseaux d'antennes intégrées actives compactes et planaires avec un amplificateur multi-étages haute puissance ont été développés avec un mécanisme de dissipateur thermique efficace. En fixant une plaque d'aluminium à l'arrière du circuit imprimé de l'amplificateur froissé, un refroidissement efficace peut être obtenu. Le comportement non linéaire de l'amplificateur s'accorde bien avec la simulation basée sur le modèle Angelov. Le circuit amplificateur haute puissance était constitué d'un amplificateur à trois étages et fonctionnait avec une puissance de sortie de 4 W pour chaque élément à 5.8 GHz. Le réseau d'antennes intégrées actives à 32 éléments a fonctionné de manière stable avec une puissance de sortie de 120 W sous la conception efficace du dissipateur thermique. Avec un poids de 4 kg, le rapport poids/puissance de sortie et le rapport volume/puissance de sortie du réseau d'antennes sont de 33.3 g/W et 54.5 cm.3/W, respectivement. La transmission d’énergie sans fil a également été démontrée avec succès.

Abstract: Compact and planar active integrated antenna arrays with a high power multi-stage amplifier were developed with effective heat sink mechanism. By attaching an aluminum plate to the backside of the creased amplifier circuit board, effective cooling can be achieved. The nonlinear behavior of the amplifier agrees well with the simulation based on the Angelov model. The high power amplifier circuit consisted of the three-stage amplifier and operated with an output power of 4 W per each element at 5.8 GHz. The 32-element active integrated antenna array stably operated with the output power of 120 W under the effective heat sink design. With a weight of 4 kg, the weight-to-output power ratio and the volume-to-output power ratio of the antenna array are 33.3 g/W and 54.5 cm3/W, respectively. Wireless power transmission was also successfully demonstrated.
