Description

一种双向均匀辐照天馈***Bidirectional uniform irradiation antenna feeder system 技术领域Technical field
本申请涉及天馈***技术领域，尤其涉及一种双向均匀辐照天馈***。The present application relates to the technical field of antenna feeder systems, and in particular, to a bidirectional uniform irradiation antenna feeder system.
背景技术Background technique
近几年高功率微波技术得到了长足的发展，而天线作为***的最前端，天线的形式、结构和性能对整个***的设计也越来越重要，本天馈***应用于高功率微波环境，频率处于UHF频段。In recent years, high-power microwave technology has been greatly developed, and the antenna is the front end of the system. The form, structure and performance of the antenna are more and more important to the design of the whole system. The antenna system is applied to the high-power microwave environment. The frequency is in the UHF band.
波导缝隙天线总的缝隙数量较多，每个缝隙的辐射较小，因此对波导内传输场的影响较小，不会造成电场增强，波导腔内的功率容量较大，此外，波导缝隙天线加工简单、精度高、结构紧凑、成本低、口径分布容易控制等，因此其在高功率微波***中得到了广泛应用。The total number of slots in the waveguide slot antenna is large, and the radiation of each slot is small, so the influence on the transmission field in the waveguide is small, the electric field is not enhanced, and the power capacity in the waveguide cavity is large. In addition, the waveguide slot antenna is processed. Simple, high precision, compact structure, low cost, easy to control the aperture distribution, etc., it has been widely used in high-power microwave systems.
波导缝隙天线是可以通过理论计算的方法，精确的计算缝隙的自导纳和缝隙间的互耦，波导缝隙天线可以通过开缝的偏置量、缝隙的宽度来调整辐射能量的大小，方便均匀照射。The waveguide slot antenna can be calculated theoretically, and the self-admittance of the slot and the mutual coupling between the slots can be accurately calculated. The waveguide slot antenna can adjust the magnitude of the radiant energy by the offset of the slot and the width of the slot, which is convenient and uniform. Irradiation.
目前微波灭活采用的是沿屏蔽舱长度方向放置波导缝隙天线，上面四根下面四根，主要的缺点有：第一，每根波导上面缝隙太多，波导缝隙天线的带宽较窄，容易导致驻波比抬升，功率利用不充分；第二，上面四根下面四根，每根波导之间的间隙较大，波导缝隙的数量较少，导致屏蔽舱内部的电磁场能量分布不均匀，而对于微波双向辐照***要求电磁场分布是越均匀越好；第三，一根波导天线对应一个频率源，整个天馈***都处于功率较大的状态，很容易出现打火现象。At present, microwave inactivation is performed by placing a waveguide slot antenna along the length of the shielded compartment, and four of the upper four. The main disadvantages are as follows: First, there are too many slots on each waveguide, and the bandwidth of the waveguide slot antenna is narrow, which is easy to cause The standing wave ratio is raised and the power utilization is insufficient. Secondly, the upper four of the above four, the gap between each waveguide is larger, and the number of waveguide gaps is small, resulting in uneven distribution of electromagnetic field energy inside the shielding cabin. The microwave two-way irradiation system requires that the electromagnetic field distribution be as uniform as possible. Thirdly, one waveguide antenna corresponds to one frequency source, and the entire antenna feeder system is in a state of high power, which is prone to sparking.
