Abstract  A novel composite right/left-handed transmission line was proposed by inserting 2-iteration Hilbert-fractal slots into a substrate integrated waveguide, in order to design compact antenna with a high peak gain. The equivalent circuit for the proposed transmission line was shown, and the circuit parameters were extracted. The dispersion diagram of the transmission line was achieved through using MATLAB. Then, a short-ended slot antenna was designed and fabricated based on the transmission line. The antenna working on the 1st order has a simple feeding network. It provides smaller electronic size and higher peak gain than reported composite right/left-handed resonant antennas. These prominent performances make it good candidate for modern wireless communication system.

Key words： composite right/left-handed transmission line      substrate integrated waveguide      fractal      slot antenna      negative-order resonant antenna

一种新型复合左右手负阶谐振天线的设计

为了获得高增益小尺寸天线,通过在基片集成波导上引入二阶Hilbert分形缝隙,提出了一种新型复合左右手传输线.在等效电路模型的基础上,利用HFSS和Serenade软件对该传输线的电路参数进行了提取；利用MATLAB语言给出了该传输线的色散曲线；最后,由该传输线设计了终端短路的缝隙天线.实验结果表明：该天线馈电网络简单,工作在复合左右手传输线的-1阶模式上,比之前报道的复合左右手谐振天线具有更小的电尺寸和更高的增益.由于这些性能,使得该天线可以用于无线通信系统中.
