Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and device for slotting a microstrip antenna. Background technique [0002] The microstrip antenna is formed by covering one side of a dielectric substrate with a thickness much smaller than the working wavelength with a metal radiation sheet, and one side is covered with a thin metal layer as a grounding plate; the radiation sheet can be designed into various shapes according to different requirements. Microstrip antenna has the advantages of light weight, small size and easy fabrication, and it has been widely used in wireless communication nowadays. [0003] However, the design of the existing microstrip antenna cannot meet the large bandwidth requirements of the 5G system, the resonant frequency does not match the center frequency, and the return loss characteristics are poor, that is, the working efficiency of the antenna is low.
