| 摘 要： | 新型无线局域网双频段微带贴片天线采用50 Ω微带线进行馈电,采用在贴片切槽设计方式，实现了微带天线在双频段工作的要求。其中心工作频率分别为2.44 GHz和5.20 GHz，相应的工作带宽分别达到了200 MHz和1.20 GHz。该天线具有小尺寸、结构简单、制作简单，低成本和在各工作频点处具有良好的方向性等优点，而且只需简单修改辐射贴片上的缝隙尺寸参数，就可以实现对天线高频段和低频段的调节。

| Abstract: | Magnetron structure and quasi magnetron structure (no cathode) are the basic elements of magnetron with diffraction output (MDO). It is the groundwork for studying the mode conversion and transmission in MDO to analyze the dispersion relation of the two types of magnetron structures. Based on the field match method, the dispersion relation of quasi magnetron is obtained, and then the relation between the wave-numbers at π mode resonant points and the geometry parameters in six cavity and two-cavity magnetron and quasi magnetron are quantitatively analyzed by numerical computation respectively. For magnetron structure, when the distance between cathode and anode is unchanged, π mode wave numbers increase with decreasing the radius of resonant cavity; when the radius of resonant cavity i |
