HB-2407BTAntenna Specifications HB-2407蓝牙天线 规格书 天线概述： 本蓝牙天线专为满足现代无线通信设备对高性能、小型化及低功耗的需求而设 计。采用先进的材料和技术，确保在蓝牙频段（2.4GHz~2.485GHz）内提供稳 定且高效的信号传输 1.Dimension（尺寸） 2.Specifications（规格） 1.工作频率范围： 核心指标：必须覆盖蓝牙技术使用的2.4GHzISM频段。 典型范围：2400MHz-2483.5MHz。这是蓝牙标准（包括经典蓝牙和低功耗蓝 牙）规定的全球通用频段。天线在这个范围内的性能必须足够好。 2.中心频率： 通常设计在频段的中心附近，例如2440MHz或2450MHz，以确保在整个工作频 段内获得相对均衡的性能。 3.带宽： 核心指标：天线在可接受性能（通常指回波损耗<-10dB或VSWR<2:1）下能够 工作的频率范围。 要求：必须大于蓝牙的信道带宽（经典蓝牙1MHz，低功耗蓝牙2MHz），且能覆 盖整个83.5MHz（2400-2483.5MHz）工作频段。设计良好的天线带宽通常要求在 80MHz或以上（在-10dB标准下）。 4.阻抗匹配： 核心指标：射频传输线（通常是50Ω微带线或共面波导）与天线输入端口间的匹 配程度。 要求：在目标工作频段内，标准阻抗为50Ω。 衡量标准： 回波损耗：通常要求在工作频段内优于-10dB（对应VSWR≈2:1），值 越小（负得越多）越好，表示反射的能量越少。更好设计能达到-15dB或 更优。 电压驻波比：通常要求在工作频段内<2:1，值越小（≥1:1）越好。 5.天线效率： 核心指标：输入到天线的射频功率有多少被有效地辐射出去（而不是损耗在导体 和介质中）。 要求：对于小型PCB天线，效率通常在30%-70%范围内（即-5dB到-1.5dB的 损耗）。目标是越高越好。效率直接影响通信距离和链路可靠性。 影响因素：PCB基板材料损耗、导体损耗、天线附近的地平面大小、布局约束、 邻近元件干扰等。 6.增益： 衡量天线在特定方向上辐射功率强度的能力（相对于理想的无损全向天线）。 对于小尺寸PCB天线（如倒F天线、蛇形天线），峰值增益通常在0dBi到3dBi 之间（甚至可能为负值）。它们通常不是高增益定向天线。 增益图（方向图）显示天线在三维空间中辐射能量的分布，蓝牙应用通常期望全向 性（在各个水平方向上辐射相对均匀）。 7.极化方式： 蓝牙通信通常使用线极化（水平或垂直），但由于设备方向多变，设计时更倾向于 实现较好的全向性而非严格的极化匹配。在PCB上，常见的倒F天线等通常是线 极化（垂直于PCB平面）。 8.尺寸： 这是PCB天线的关键优势之一。 典型尺寸约为1/4波长（在FR4基板上有效波长约为30mm），长度范围通常 在1 1 mm-30mm之间。宽度和形状根据具体设计（倒F、曲折线、蛇形、PIFA 等）变化。 3.Gain（增益） 增益：1.6dBi 4. Bandwidth （带宽） 带宽：150MHZ 5．AntennaDATA（天线数据）
