frequency band range

基本解释

The spectral compressor compresses a pre-selected portion of the high frequency band and maps the compressed high frequency band to a lower band limited frequency range.
频谱压缩器压缩高频频带的预选择部分，并将压缩的高频频带映射到较低的有限带宽频率范围。

Thus, the size of the dielectric antenna can be reduced and the dielectric antenna can have a wide range of a frequency band suppressing the maximum value of the VSWR to a small value.
由此，能够实现介电体装载天线的小型化，并且在该介电体装载天线中，可实现将VSWR的最大值抑制得较小的频率频带的宽频带化。
