Embodiment Construction
[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0023] This application discloses a new broadband single-layer patch antenna, please refer to figure 1 , the novel broadband single-layer patch antenna includes a dielectric substrate 2, a metal formation 1 disposed on the lower surface of the dielectric substrate 2, and a rectangular patch radiator 3 disposed on the upper surface of the dielectric substrate 2, the metal formation 1, the dielectric substrate 2 and The rectangular patch radiator 3 is arranged parallelly from bottom to top to form the main structure of the single-layer patch antenna. Only a single-layer patch is used to avoid the use of an adhesive layer, which simplifies the antenna structure, is easy to process, and has low cost. The parameters of the dielectric substrate 2 are important factors affecting the bandwidth of the antenna. Smaller dielectric constant and thicker ...

Abstract
The invention discloses a novel broadband single-layer patch antenna, and relates to the technical field of antennae, the patch antenna comprises a metal ground layer, a dielectric substrate and a rectangular patch radiator which are sequentially stacked from bottom to top, two ends of a diagonal line of the rectangular patch radiator are respectively provided with a cut corner, and the corner cuts are in central symmetry; a group of parasitic patches are respectively arranged at each corner cut to be coupled with the rectangular patch radiator, and a feed connector penetrates through the metal ground layer and the dielectric substrate to be connected with the rectangular patch radiator for feeding; according to the patch antenna, the bandwidth of the antenna can be expanded, the gain is not sacrificed while the frequency band of the antenna is expanded, the profile property of the antenna is changed, only a single-layer patch is used, the use of a bonding layer is avoided, and the patch antenna has the advantages of being large in bandwidth, high in gain, simple in antenna structure, easy to process and the like.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a novel broadband single-layer patch antenna. Background technique [0002] Microstrip patch antennas are widely used in military and civilian fields because of their significant advantages such as low profile, light weight, and easy processing. However, the main disadvantage of the microstrip patch antenna is its narrow bandwidth. The bandwidth of a typical microstrip patch antenna with a VSWR of less than 2 is only about 4%. The narrow bandwidth limits its application in many occasions. Contents of the invention [0003] The inventor proposes a novel broadband single-layer patch antenna for the above-mentioned problems and technical requirements, and the technical scheme of the present invention is as follows: [0004] A novel broadband single-layer patch antenna, the novel broadband single-layer patch antenna includes a dielectric substrate, a metal formation arranged on t...
