2022年8月25日，FCC发布Zui新公告，即日起所有FCC Part 15的FCCID申请资料均需提供天线信息或者天线报告，至少要包含Zui大增益、天线方向图、用于识别设备内部天线的图片或绘制图等信息，报告中将不再接受客户宣称的天线增益的说法。没有上网的各类WiFi,Bluetooth,Zigbee,Lora,UWB等产品目前上网均需提供符合要求的天线报告。
除了Part 15标准以外：任何需要测试场强的标准，例如常见的FCC part15.225,15.227,15.229,15.231,15.239,15.249等标准，并不需要提供天线信息或者天线报告，但需要体现天线的照片、尺寸等信息在报告里面或者产品照片上。
特别说明的是：由于一些商业保密需求，有必要剔除相关保密的信息，如设计原理等可以从报告中删除，或者整个天线报告可以进行保密。但天线增益的信息是公开的，如果天线报告只包含Zui大增益、天线方向图、用于识别设备内部天线的图片或绘制图，FCC不被视为可保密的信息。

URGENT CLARIFICATION-FCC Area of Concern-Antenna GainInformation
Please see the updated notice regarding Antenna GainInformation
Any applications granted after August 25,2022 that do notcontain the proper antenna information will be dismissed.
This email is to bring to your attention that while the FCChas been advising test labs and TCBs to make sure part 15applications includes antenna gain data sheets and/or testreports,it is evident by recent audits that this information isbeing omitted.
We are still finding reports that state,"antenna gaininformation is declared by the manufacturer",with no othersupporting information.As we have re-iterated during the last TCBworkshop,this statement will not suffice.All part 15 applicationswill need to show how the antenna gain was derived either from amanufacturer data sheet or a measurement.Where the gain of theantenna is inherently accounted for as a result of themeasurement,such as field strength measurements on a part 15.249 or15.231 device,so the gain does not necessarily need to beverified.However,enough information regarding the construction ofthe antenna shall be provided.Such information maybephotographs,length of wire antenna etc.
The antenna gain information shall be made public(notconfidential).Any proprietary information such as constructionmaybe stripped from the gain information report and heldconfidential.The main antenna information we require is the maximumgain of the antenna for the band of operation.This information mustbe provided as a data sheet or a measurement report.
