| Abstract | 本实用新型涉及一种漏波天线，包括微带漏波天线和全通滤波器，微带漏波天线包括微带线和与微带线连接的贴片单元，全通滤波器包括介质底板和短截线，微带线、贴片单元和短截线周期性间隔排列设置于介质底板，各贴片单元通过对应的微带线连接相邻的贴片单元，各短截线与对应的微带线正交对称耦合设置，介质底板与各短截线对应的位置开设有槽，槽的宽度与对应短截线的宽度的误差小于预设误差，槽的长度大于短截线的长度。通过调节短截线的长度使得在微带漏波天线工作带宽内具有较高的群时延特性，将具有较高的群时延特性的全通滤波器耦合级联进微带漏波天线，通过增大微带漏波天线的群时延，大幅提高在相同带宽下微带漏波天线的扫频角度范围。 |
| Other Abstract | The utility model relates to a leaky -wave antenna, including microstrip leaky -wave antenna and all pass filter, microstrip leaky -wave antenna includes microstrip line and the paster unit of being connected with the microstrip line, all pass filter includes medium bottom plate and stub, the microstrip line, the periodic interval arrangement of paster unit and stub sets up in the medium bottom plate, adjacent paster unit is connected through the microstrip line that corresponds to each paster unit, each stub and the microstrip line quadrature symmetry coupling setting that corresponds, the medium bottom plate is seted up slottedly with the position that each stub corresponds, the error of the width in groove and the width that corresponds the stub is less than predetermines the error, thelength in groove is greater than the length of stub. Make through the length of adjusting the stub to have higher group delay characteristic in microstrip leaky -wave antenna work bandwidth, into microstrip leaky -wave antenna is cascaded in the all pass filter coupling that will have higher group delay characteristic, through increase microstrip leaky -wave antenna's group delay, improves microstrip leaky -wave antenna's under the same bandwidth frequency sweep angle scope by a wide margin. |
