Problems solved by technology
[0003] Although the existing microstrip antenna 1 has many characteristics, such as small size, light weight, low profile (profile), easy integration with subsequent circuits, etc., because the conductor radiation patch 13 and the conductor of the microstrip antenna 1 itself The shape of the ground plate 12 limits the current distribution of the fed electrical signal on the surface of the conductor radiation patch 13, thus only causing specific frequency radiation, resulting in a narrow operating bandwidth, thereby limiting its application range

A broadband microstrip antenna comprises an insulated substrate, a grounding sheet and a radiation sheet, wherein the insulated substrate is provided with a first surface and a second surface opposite to the first surface; the grounding sheet is formed by a conductor material and is formed on the first surface; the radiation sheet is formed by the conductor material and formed on the second surface and comprises a feed-in arm extending inwardly from the edge of the second surface, crossing the grounding sheet and enabling an electric signal to be inputted, a radiation body extending towards the direction, away from the grounding sheet, from the feed-in arm and a notch extending towards a first direction from one side of the radiation body; and the notch enables the side of the radiation body to be in a winding shape to further change the current distribution on the surface of the radiation body. Thus, a high-operation broadband is provided.
Description
technical field [0001] The invention relates to an antenna, in particular to a broadband microstrip antenna with high operating bandwidth. Background technique [0002] refer to figure 1 , the existing microstrip antenna 1 (patch antenna) includes a dielectric substrate 11, a conductor ground patch 12 formed on the dielectric substrate 11, a conductor radiation patch formed on the dielectric substrate 11 and opposite to the conductor ground patch 12 sheet 13 (patch), and a feeding arm 14 extending inwardly from the surface edge of the dielectric substrate 11 to the conductor radiation patch 13 and inputting a power supply signal, when the electrical signal is fed from the feeding arm 14 to the conductor radiating patch 13, and when an electromagnetic field is excited between the conductor radiating patch 13 and the conductor grounding patch 12, the electromagnetic field can be radiated to space through the gap around the conductor radiating patch 13 and the conductor ground...
