器件名称: R&S®HL046E 天线
功能描述: R&S®HL046E 高增益对数周期天线具有出色的宽带特性，辐射特性接近旋转对称，高增益，尤其适合进行 EMS 抗扰度测量。
与现有系统相比，它能够在放大功率较低的情况下获得所需场强，原因在于其高增益。
由于它外形小、频率范围宽、可折叠，因而尤其适合在测试室内使用。

antenna gain, i.e. low amplifier power is required change of antennas needed over wide frequency range JJ Uniform object irradiation due to optimized radiation patterns JJ Small size JJ Influence of chamber reduced JJ Antenna gain approximately constant over the whole frequency range JJ Can be wall-mounted Brief description The R&SHL046E high gain log-periodic antenna offers excellent broadband characteristics, a radiation pattern that is approximately r otation-symmetrical as well as high gain, making it particularly suitable for EMS immunity measurements. In comparison with existing systems, the required field strengths can be achieved with a lower amplifier power. This is due to the high antenna gain. Its small size, wide frequency range and folding mechanism make the antenna ideal for use in test chambers.
