摘要（英）：

The invention discloses an X-band negative magnetic permeability material wide band microstrip antenna and a manufacturing method thereof. The antenna includes a first dielectric substrate, a second dielectric substrate, a U-shaped slot patch antenna, a metal grounding plate and an SMA coaxial connector, wherein the first dielectric substrate is connected with the second dielectric substrate, thefirst dielectric substrate is located above the second dielectric substrate, an air cavity is disposed between the first dielectric substrate and the second dielectric substrate, multiple open resonant rings are disposed on an upper surface of the first dielectric substrate and are periodically arranged, a U-shaped slot patch antenna is disposed on an upper surface of the second dielectric substrate, a lower surface is connected with the metal grounding plate, one end of the SMA coaxial connector is connected with the U-shaped slot patch antenna, and the other end is connected with the metal grounding plate. The antenna is advantaged in that the side feed U-shaped slot patch antenna is combined with the open resonant ring array technology, the meandering band spread technology is combinedwith the theory that negative permeability materials inhibit lateral radiation, and the microstrip patch antenna implementing X-band wideband and high gain functions is achieved.
