基于PowerHelix专利滤波技术,SL1350最适合于移
动电话、数码相机、运动手表以及那些集成了GPS且需要精确定
位的内部无线电环境复杂的设备。SL1350能帮助用户的产品提升接收能力。
产品介绍
SL1350适合的应用
手持、穿戴设备及其他存在高介电材料的环境,该环境下通常会使传统天线出现失调。
一起集成的还有其他类型的天线,如蓝牙/GPS接收器,WIFI/GPS数码相机或GPS/GSM移动电话。
设备尺寸或预留给天线做反射区的空间严格受限,SL1350不需要反射区。
设备无固定的方向(方向的变动比较随机)或天线需要集成到设备中。
SL1350天线进行了静电平衡处理(静电平衡的导体介质中电场强度为零),从而能够将其与设备隔离起来,
并且抵抗来自于设备中的常见噪音信号。由于SL1350的构造和所使用的材料的原因,其近场被限制在很小的
范围内,因而天线周围的材料所产生的失调影响几乎可以忽略不计。SL1350与SL1300采用了同样的尺寸设计和
陶瓷元件,但却有多项提高,包括:
双频,允许从同一天线接收GPS和2.45GHz的信号
只使用1个天线就可能部署GPS/WiFi/2.45GHz三个无线频段
产品进行了加固升级,能承受更高的应力
简化了安装,可使用简单的连接器或焊接到用户基板上

集成后辐射分布图
相比在自由的空间中,集成后SL1350的增益提高了约2~3个dB。天线
与PCB板间的1.5mm的间距非常有必要,因为这是天线近场能量反射,
产生天线增益所需要的。从集成后的天线辐射图可以看出强烈的右
旋圆极化特征以及3dB大波束角下增益的典型峰值为-3dBic。
PowerHelix天线技术能对抗像人体组织这样电介质带来的失调影响,
集成后的SL1350的性能提高了一倍,而普通的天线在类似的环境下
则会损失5~10个dB。
典型阻抗
SL1350进行过优化,以简化匹配环节,天线的阻抗为50Ω。内部的双频
匹配电路保证了天线在GPS和2.45GHz模式下的阻抗都能达到50Ω。左边
是史密斯阻抗曲线图,已经标准化到1。SL1350的进场能限制在陶瓷中,
距离内。
其他材料或人体组织对阻抗的影响完全可以忽略,除非它们是在天线外

38.5mm
天线增益
参数表中SL1350的增益是在PCB板安装,1.5mm的间距条件下得到的。左图展示了使用PCB安装
时的一种情况。由于PCB与天线能够靠的非常近,因此,在PCB板上毗邻天线处的地方可以安
装其他电子元件。但无论安装的是何种材料或者元件,最小间距不可小于1.5mm。靠近天线处
PCB板的最低宽度推荐不小于25mm。
左图是关于减小天线毗邻区PCB板面积时对增益的影响。曲线
图反应的是当PCB板的宽度从最大38.5mm逐步减小到最小5mm
的情形。在宽度为38.5mm时,天线的增益为-3dBic,当到达
25mm时,增益减小为约-4.3dBic。
SL1350是为空间有限的集成应用设备而设计。为了能够使产品
获得良好的GPS性能,我们推荐给天线旁的PCB板至少留下25mm的宽度。
SL1350在与GPS芯片连接时不需要进行解调(天线连接好后就已
经同频了),鉴于此,请用户认真阅读产品机械安装指南以
确保性能。为了保证天线在安装位置稳定,还需要额外采取
措施加固。更多有关天线安装信息,参见产品机械安装指导说明。
右图是采用手工焊接的方式将天线安装到用户PCB板上的示意图。
