这封信涉及使用超宽带惠勒帽（UWB WCap）和混响室（RC）来测量窄带天线的效率。这是第一个为宽带系统设计的试验台，也可以精确地测试窄带天线。第二个，最初设计用于电磁兼容性（EMC）测量，提供了测量天线效率的优势。给出了评估两种测量方法的不确定度和准确性的结果。
This letter deals with using ultrawideband (UWB) Wheeler Cap (UWB WCap) and reverberation chamber (RC) to measure efficiencies of narrowband antennas. This first testbed designed for very broadband systems can also be accurate for narrowband antennas. The second one, first designed for electromagnetic compatibility (EMC) measurements, offers advantages to measure antenna efficiency. Results are given to assess uncertainty and accuracy of both measurement means.
