一种高功率微波宽带紧耦合偶极子阵列天线
A tightly coupled dipole array antenna with high power and broadband
摘要
Abstract
A novel tightly coupled dipole array antenna with high power and broadband is proposed in this paper.On the basis of conventional tightly coupled dipole array antennas,and by adopting an all-metal structure design,an integrated design of antenna matching layer and sealing layer,and a method of adjusting the antenna structure,a high-power and broadband performance of such an array antenna is obtained.The simulation results show that the standing wave ratio of the array antenna is less than 2 at the broadside in the range of 0.8-4.0 GHz.And the power capacity of an element antenna reaches 0.12 MW within the size of 16 mm×32 mm in the space full of SF6 at one atmospheric pressure.Moreover,the power capacity of the 10×10 array antenna composed of 100 elements can reach 12 MW within the size of 320 mm×640 mm in the space full of SF6 at one atmospheric pressure.In addition,the array antenna can achieve a wide-angle scan of 45°.The proposed array antenna provides a solution for high-power microwave broadband antennas to achieve a broadband,large-angle scanning,compact,miniaturized,and low-profile performance.关键词
