Description

轻小型测量天线装置Light and small measuring antenna device 技术领域Technical field
本发明涉及天线技术领域，特别涉及一种空气介质型轻小型测量天线装置。The present invention relates to the field of antenna technologies, and in particular, to an air medium type small and small measuring antenna device.
背景技术Background technique
传统微带天线由于带宽窄，尤其是低介电常数的介质作为天线基板材料时，低仰角增益较低，造成天线对低角度卫星信号接收性能较差；虽然高介电常数的介质可以提高波束带宽，但会导致天线的带宽变窄。如此，需要采用双层结构或多层结构才可以实现天线的双频L1(1521MHz～1620MHz)和L2(1160MHz～1300MHz)卫星信号良好接收。然而，传统的层叠式双频天线装置，又难以实现天线轻小型化结构设计，并且成本较高。Due to the narrow bandwidth of the traditional microstrip antenna, especially when the low dielectric constant medium is used as the antenna substrate material, the low elevation angle gain is low, resulting in poor antenna reception performance for low angle satellite signals; although high dielectric constant medium can improve the beam. Bandwidth, but will cause the bandwidth of the antenna to be narrowed. In this way, it is necessary to adopt a two-layer structure or a multi-layer structure to achieve good reception of the dual-frequency L1 (1521 MHz to 1620 MHz) and L2 (1160 MHz to 1300 MHz) satellite signals of the antenna. However, the conventional stacked dual-frequency antenna device is difficult to realize the lightweight and compact structure design of the antenna, and the cost is high.
通常，为了增加带宽要求，需要将传统微带天线中介质基板增厚，一般要达到6mm～12mm。但这样天线表面的表面波增加，将影响天线性能；同时产品重量以及成本均会相应增加；而如果单层介质增加到7mm以上，加工难度和精度变大，加工成本高，随之也会造成产品不良率增加和几何对称性变差。Generally, in order to increase the bandwidth requirement, the dielectric substrate in the conventional microstrip antenna needs to be thickened, generally reaching 6 mm to 12 mm. However, the surface wave of the antenna surface will increase, which will affect the performance of the antenna. At the same time, the weight and cost of the product will increase accordingly. If the single layer medium is increased to more than 7mm, the processing difficulty and precision will become larger, and the processing cost will be high, which will also cause Product defect rate increases and geometric symmetry deteriorates.
