The present invention relates to a bifunctional angiogenesis inhibitor, which has VEGF inhibitory activity and FGF inhibitory activity, and can inhibit VEGF and FGF dual factors-induced or high glucose-induced cell proliferation, cell migration, and/or lumen formation. The present invention also relates to the use of the bifunctional angiogenesis inhibitor in inhibiting retinal angiogenesis, such as diabetic retinopathy, age-related macular degeneration and the like.

Bifunctional angiogenesis inhibitor and use thereof

The present invention discloses a four-mode defected ground structure resonator, comprising a metal dielectric substrate and a defected ground unit which is etched in one surface of the metal dielectric substrate; the shape of the defected ground unit is axially symmetric about a first central axis of the defected ground unit, and also the shape of the defected ground unit is axially symmetric about a second central axis of the defected ground unit; the first defected ground unit is provided with H-shape or quasi H-shape, the second defected ground unit is provided with L-shape, quasi L-shape, U-shape or quasi U-shape. The four-mode defected ground structure resonator of the present invention is provided with four types of resonant modes, and the four types of resonant modes are provided with good tunability.

Four-mode defected ground structure resonator

Disclosed is a four-mode defected ground structure filter, including a four-mode defected ground structure resonator and two microstrip feed lines. The four-mode defected ground structure resonator comprises a metal dielectric substrate and a defected ground unit which is etched in one surface of the metal dielectric substrate; the microstrip feed lines are arranged at another surface of the metal dielectric substrate; shape of the defected ground unit is axially symmetric about a first central axis of the defected ground unit, and is axially symmetric about a second central axis of the defected ground unit; the first defected ground unit is provided with H-shape or quasi H-shape, the second defected ground unit is provided with L-shape, quasi L-shape, U-shape or quasi U-shape.
