摘要

本文提出了一种基于非对称共面波导结构的新型谐振天线。在确定的几何结构下，在复合左/右传输线模型中引入谐振环可以提高带宽。效率和几何增益可以通过结合梳状驱动类型的结构来提高，该结构引入了数字间电容并产生了更多的谐振频率。不对称地平面将尺寸减小到38.5×25 mm。获得了覆盖阻抗带宽(2.34-2.55 GHz)的双频段，低频段210 MHz和(3.2-3.8 GHz)，高频段600 MHz对应的分数带宽分别为8.7%和16.3%。天线几何结构非常高效，最高效率为99%，峰值增益高达4.23dBi。自定义天线非常适合于WLAN/LTE应用。

Asymmetric coplanar waveguide-fed CRLH-TL based antenna for WLAN/LTE applications

In this paper a novel type of resonant antenna based on asymmetric coplanar wave guide structure has been presented. In the defined geometry bandwidth can be increased by introducing resonator ring in composite right/left handed transmission line model. Efficiency as well as gain of the geometry can be improved by incorporating comb drive type of structure which introduces interdigital capacitors and produces one more resonant frequency. Asymmetric ground plane reduced the dimensions up to 38.5×25 mm. Dual band have been obtained covering impedance bandwidth of (2.34-2.55 GHz), 210 MHz in lower band and (3.2-3.8 GHz),600 MHz in higher band corresponds fractional bandwidth of 8.7% and 16.3%. Antenna geometry is highly efficient showing maximum efficiency of 99% and peak gain up to 4.23dBi. Defined antenna is very suitable for WLAN/LTE applications.
