摘要:

提出了一种波导带状线转换器，应用于毫米波多层微带阵列天线设计，减小了天线的厚度，并增加了天线的效率和可靠性。与采用传统的波导微带转换器、微带同轴转换器及同轴带线转换器的级联转换方案的天线相比，该多层微带阵列天线的厚度缩小了90％，实测为 12 mm，天线效率增加了14％，实测为24％。

关键词: 毫米波微带阵列天线波导带线转换器；天线效率

Abstract:

A waveguide to stripline transition is used in the design of mill imeter wave(MMW) multilayer microstrip array antenna to reduce the thickness of antenna and enhance its efficiency and reliability.Compared with the antenna u sing the series scheme of waveguide to microstrip line transition, microstrip to coaxialline transition, and coaxialline to stripline, the multilayer micros trip array antenna using the scheme of waveguide to stripline transition has the thickness of 1.2mm with the decrease of 90%，and the efficiency of 24% w ith the increase of 14%.

Key words: millimeter wave microstrip array antenna waveguide to stripline transition antenna efficiency
