The invention discloses an arched stretchable antenna array feed network, which comprises: a dielectric substrate and at least two radiation patches, wherein each radiation patch is arranged above thedielectric substrate; at least two microstrip feeder line assemblies, wherein each microstrip feeder line assembly is arranged above the dielectric substrate, and each microstrip feeder line assemblyis connected with one corresponding radiation patch; and a micro-strip one-to-four power dividing assembly which is arranged above the dielectric substrate, wherein the micro-strip one-to-four powerdividing assembly is connected with each micro-strip feeder line assembly, the dielectric substrate, the micro-strip feeder assembly and the micro-strip one-to-four power dividing assembly can be stretched and deformed along the transverse direction or the longitudinal direction. According to the invention, the antenna array feed network has a stretchable characteristic, is large in stretchable range and high in conductivity, and can be applied to wearable equipment, portable systems and object surfaces with special shapes.
Description
technical field [0001] The present invention relates to the technical field of antenna manufacturing. More particularly, the present invention relates to an arched stretchable antenna array feed network. Background technique [0002] In the field of antenna manufacturing technology, it is well known to use antenna array feeding networks of different structures to implement antenna feeding. In the process of researching and implementing antenna feeding, the inventor found that the antenna array feeding network in the prior art has at least the following problems: [0003] The existing antenna array is made on a rigid dielectric substrate, and the feed network is also made on the rigid substrate, which has poor tensile performance and cannot meet the needs of existing equipment. At the same time, the existing antenna array feed network The bandwidth is narrow and cannot meet the needs of existing equipment. [0004] In view of this, it is necessary to develop an arch-shaped...
