摘要：

为满足无人机集群通信天线的双频带、集成共形的应用需求,设计并制作了一种新型一体化机翼共形天线。该天线采用偶极子天线单元和LC高低通双工器合并实现。天线单元采用三对开路分支线实现有效扼流,并保证宽带全向辐射,双工器采用K-m型LC滤波器,实现低插损、高抑制的双通道工作。天线在L、S两个工作频带内实测电压驻波比(Voltage Standing Wave Ratio,VSWR)小于2,增益大于0 dBi,频带间隔离度优于30 dBc。针对高速率传输需求的无人集群数据链系统,仅加装1部垂尾翼共形天线,即可支撑双频段同时工作。天线整体集成于无人机的单个垂尾翼内,有效提升了无人集群系统的平台集成能力,在无人机领域具有广泛的应用前景。

Abstract:

In order to meet the demands of dual-band and integrated conformal antenna for UAV (Unmanned Aerial Vehicle) swarm communication systems, an integrated wing conformal antenna is designed and fabricated. The antenna is realized by combining a broadband dipole antenna and a low-pass and high-pass LC combiner. The antenna element is realized by three pairs of open branch lines to achieve effective choking characteristics and broadband omnidirectional radiation. The combiner consists of K-m LC filters, which are used to realize dual-band operation with low insertion loss and high rejection. The measured Voltage Standing Wave Ratio(VSWR) of antenna is less than 2, the measured gain is more than 0 dBi, and the isolation is better than 30 dBc between L and S frequency band. By mounting only one wing conformal antenna, a dual-band simultaneous operation can be realized which meets the need of UAV swarm data link system for high communication rate. The proposed antenna is whole arranged in the tail wing of UAV to enhance the integration capability of the UAV swarm, and can be widely used in UAV field.
