KH-2012-HM1 2.4GHz陶瓷天线产品概述

一、产品定位与核心应用场景

KH-2012-HM1是金航标(Kinghelm)针对超小体积、低功耗无线终端推出的内置陶瓷天线,核心定位是“紧凑空间下的稳定信号传输解决方案”。其设计重点是平衡“微型化”与“射频性能”,解决传统外置天线占空间、易损坏的痛点,适配对尺寸敏感的场景——比如可穿戴设备、智能家居传感器、小型物联网模块等。

二、关键性能参数详解

  1. 频率覆盖:中心频率2.45GHz,带宽100MHz(覆盖2.4~2.5GHz),精准匹配当前主流2.4G无线协议(蓝牙、WiFi、ZigBee、Thread等),无需额外频偏补偿,直接对接射频模块。
  2. 信号增益:3.12dBi的增益在同尺寸陶瓷天线中属于中等偏上,相比部分2dBi以下的小天线,能提升10%15%的信号覆盖距离(室内场景约58米稳定传输)。
  3. 阻抗与驻波比:50Ω标准射频阻抗,与90%以上的无线模块(如CC2530、ESP8266)完美匹配;驻波比(VSWR)≤2,意味着信号反射损耗低于10%,传输效率有保障。
  4. 尺寸规格:2mm×1.2mm×0.5mm的超小体积(约指甲盖1/10大小),完全适配0805封装的贴片工艺,可塞进可穿戴手环、智能门锁等狭小空间。

三、结构设计与封装优势

  1. 陶瓷介质特性:采用高介电常数陶瓷材料,相比传统PCB天线,介质损耗更低(约0.001),信号衰减小;同时陶瓷耐温性强(可承受260℃回流焊温度),适配SMT自动化生产,无需额外手工焊接。
  2. 0805封装适配:贴片式设计,引脚与常规0805电阻/电容一致,可直接集成到PCB板任意位置(无需预留额外天线空间),大幅提升产品集成度。
  3. 抗干扰能力:陶瓷天线辐射方向图更集中(半功率角约60°),能减少周边数字电路的电磁干扰,适合复杂电路环境下的稳定工作。

四、兼容性与适用环境

  • 协议兼容:全面支持蓝牙4.0/5.0、WiFi 2.4G(802.11b/g/n)、ZigBee 3.0、Thread等低功耗无线协议,覆盖当前物联网主流通信标准。
  • 设备适配:
    • 可穿戴:智能手环、手表、运动追踪器(不影响佩戴舒适度);
    • 智能家居:温湿度传感器、智能门锁、无线开关、扫地机器人传感器;
    • 工业物联网:小型无线传感器(车间环境监测)、低功耗数据采集终端;
    • 消费电子:无线遥控器、蓝牙耳机(入门级)、小型蓝牙音箱。
  • 环境适应性:陶瓷材料耐湿、耐老化,适合室内常规环境(温度-20℃+85℃,湿度10%90%RH),不建议长期暴露在户外强紫外线或极端潮湿环境。

五、典型应用案例参考

  1. 智能手环集成:某品牌运动手环将KH-2012-HM1内置在表带扣附近,仅占用0.5mm厚度空间,实现蓝牙5.0稳定连接(手机距离5米内信号强度≥-65dBm),续航提升10%(无需额外供电)。
  2. 智能家居温湿度传感器:某IoT厂商的壁挂式传感器采用该天线,无需外接天线,外观简洁;在多层住宅中,信号可穿透1层石膏墙,稳定传输至网关。
  3. 工业无线传感器:某制造车间的温度传感器集成该天线,部署在设备缝隙中,抗干扰能力满足车间电磁环境(周边有电机、变频器),数据丢包率低于1%。

KH-2012-HM1以“微型化+高性价比”成为小体积无线设备的优选天线,解决了紧凑空间内的信号传输痛点,适配多种主流无线协议与应用场景。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
