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。
