【摘要】 本文介绍一种双频宽频带定向印刷天线。该天线通过增加反射底板与金属挡板实现定向辐射。测试结果表明,在800-960MHz及1710-2690MHz频带内VSWR小于1.5。同时在800-960MHz增益大于6dBi,1710-2690MHz增益大于7dBi。该天线具有良好的阻抗匹配与定向辐射特性,可用于现代无线通信系统。更多还原

【Abstract】 A dual-band directional printed antenna is presented in this paper. The proposed antenna can realize directional radiation by adding the reflection plate in the back of the antenna. Simulated and measured results show that the antenna works well in the frequency band. The VSWRs are less than 1.5 in 800-960 MHz and 1710-2690 MHz while the gains are more than 6 dBi in 800 MHz-960 MHz and 7 dbi 1710 MHz-2690 MHz. The proposed antenna has good impedance and radiation characteristics in the whole frequency band. It can be widely used in wireless communication Systems.更多还原
