Abstract
The invention discloses a strip line-based coaxial feed microstrip antenna, which relates to the technical field of microwave millimeter communication and comprises a first metal layer, and a first dielectric layer, a second metal layer, a second dielectric layer, a third metal layer, a third dielectric layer and a parasitic patch antenna sequentially positioned on one side of the first metal layer, wherein the first dielectric layer internally comprises a strip line, and the strip line extends in the direction parallel to the plane where the first metal layer is located; the second metal layer comprises a first opening; the second dielectric layer comprises a via hole and a plurality of first through holes; the orthographic projection of the via hole is located in the first opening in the direction perpendicular to the plane where the first metal layer is located; the third metal layer comprises a second opening, and the orthographic projection of the radiation patch antenna is located in the second opening in the direction perpendicular to the plane where the first metal layer is located; and the second metal layer is connected with the third metal layer through the first through hole. The strip line is connected to the radiation patch antenna through the via hole and feeds, so that the gain and the bandwidth of the microstrip antenna are improved.
Description
technical field [0001] The invention belongs to the technical field of microwave and millimeter communication, and in particular relates to a stripline-based coaxial feeding microstrip antenna. Background technique [0002] With the development of modern processing technology, a new type of planar antenna represented by the microstrip antenna has gradually formed. The microstrip antenna has the advantages of low cost, easy mass production, small size, low profile, and can be applied to dual polarization, multi-band, Multi-beam and other environments. [0003] Antenna-in-Package (AiP) technology is a technology that integrates three-dimensional multi-chip components and radio frequency antennas based on packaging materials and processes, with the purpose of realizing the miniaturization design of system-level communication. The antenna-in-package technology integrates the package cavity around the antenna and mounts multi-chip components inside to realize the integrated desi...
