基于复合左右手结构的零阶谐振小型天线设计

内容简介：论文中提出了一种基于复合左右手结构的零阶谐振小型天线，由四个等腰三角形贴片对称排列而成。使用软件仿真和优化得到天线零阶谐振频率为4.7GHz，并给出了各单元的具体参数。仿真结果，在中心频率4.7GHz处，天线的电压驻波比为1.16，天线增益为6.8dB，半功率波瓣宽度为83.1度。

Abstract：A kind of?zero-order resonator?small?antenna based on the composite right/left -handed structure is presented in this paper, and it is composed of four isosceles triangular patch by symmetrical arrangement. The zero-order?resonance frequency of the antenna is 4.7GHz by the simulation and optimization,?and the specific?parameters of each?unit are given. Simulation results show that this antenna could achieve gain of 6.8dB and VSWR of 1.16 at a center frequency of 4.7GHz, and the half-power beam-width of 83.1 degrees.
