| 英文摘要 | 针对室内走廊或狭长街道小功率基站应用要求,采用微带结构设计了一款具有双向辐射特性的宽带线极化低剖面天线。天线辐射元为平行四边形结构,馈电点在其几何中心,通过在靠近馈点两侧开两个反对称l形槽,实现了宽带双向辐射特性。低剖面原型天线的相对带宽为5.8%,两端射方向增益约为4.3dbI,在工作频带内天线辐射场为有一定倾角的线极化。该天线结构可置于小功率基站内部,有助于减少系统体积。; A linearly polarized wideband microstrip patch antenna with the bi-directional radiation pattern is proposed for the low-power indoor or narrow-street base station systems.The proposed antenna,which has a parallelogram radiator,is fed by a coaxial line at its geometric center.In order to achieve the wideband bi-directional radiation characteristics,two anti-symmetric L-shaped slots were etched near the feed point.The simulation and measurement show that the low profile prototype antenna provides a relative bandwidth of about 5.8%,and the endfire direction gain of 4.3dBi.In the working band its linear polarization direction has incline angles with the vertical.This antenna can be placed inside the low-power base stations to help reduce the system size.; 福建省重大科技专项(2010HZ0004-1) |
