摘要：【中文】本发明公开了一种开环槽相互嵌套加类U形槽的七陷波微带天线结构，第一弧形开环谐振器与第二弧形开环谐振器的形状不同，第二弧形开环谐振器与第三弧形开环谐振器形状不同；第一类U形寄生带与第二类U形寄生带的间距为0.9mm；第三类U形寄生带与第四类U形寄生带间距为1mm；微带馈线两侧的类U形寄生带与微带馈线的间距不相同；第一类U形寄生带连接臂长度为6.1mm；第二类U形寄生带连接臂长度为6.6mm；第三类U形寄生带连接臂长度为6.5mm；第四类U形寄生带连接臂长度为6.5mm。以解决现有技术一是现有技术中并没有能够实现7陷波的陷波天线；二是现有的陷波天线的各陷波结构间存在强烈耦合的问题。 【EN】The invention discloses a seven-notch microstrip antenna structure with U-shaped grooves embedded in open-loop grooves, wherein a first arc-shaped open-loop resonator and a second arc-shaped open-loop resonator have different shapes, and the second arc-shaped open-loop resonator and a third arc-shaped open-loop resonator have different shapes; the distance between the first U-shaped parasitic strip and the second U-shaped parasitic strip is 0.9 mm; the distance between the third U-shaped parasitic strip and the fourth U-shaped parasitic strip is 1 mm; the distances between the U-shaped parasitic bands at the two sides of the microstrip feeder line and the microstrip feeder line are different; the length of the first U-shaped parasitic band connecting arm is 6.1 mm; the length of the connecting arm of the second U-shaped parasitic belt is 6.6 mm; the length of the connecting arm of the third U-shaped parasitic belt is 6.5 mm; the length of the connecting arm of the fourth type of U-shaped parasitic band is 6.5 mm. The trap antenna aims to solve the problems that no 7 trap antenna can be realized in the prior art; secondly, the problem of strong coupling exists among all trapped wave structures of the existing trapped wave antenna.
