    OTA天线性能测试简介

测试规范:

1. CTIA的OTA规范(Testing Plan for Mobile Station Over the Air Performance v2.2);

2. 3GPP/ETSI OTA antenna performance conformance testing测试标准(TS 34.114) ;

3. 中国信产部的YD 1484-2006-1(移动台空间射频功率和接收机性能测量方法/Measurement Method for Radiated RF Power and Receier Perfomance of Mobile Staton)标准;

4. 无源天线测试(Passive antenna test)。

系统测试能力(Testing capability)

1. 有源(Active)

TRP (Total Radiated Power)/总发射功率;TIS(Total lsotopic Sensitivity)/接收灵敏度;

NHPRP(Near Horizon Partial Radiated Power)/近水平面发射功率;NHPIS(Near Horizon lsotropic Sensitivity)/近水平面接收灵敏度;

EIRP(Effective lsotropic Radiated Power)/ERP(Effective Radiated Power)/等效全向辐射功率;PEIRP(Peak Effective lsotropic Radiated Power)/峰值等效全向辐射功率。

2. 无源(Passive)

Gain(dBi): Gain(dBd)/增益;

Radiation Pattern/天线方向图测试;

Input lmpedance /天线接口阻抗测试;

VSWR/RL/天线驻波比/回波损耗测试;3D/3D场强图;

3dB BW/FB Ratio波束宽度，前后比;

Cross polar/lsolation交叉极化比，隔离度;Directivity/方向性;

Efficiency效率。
