Измерение амплитудной диаграммы направленности и частотной характеристики антенн ISM-диапазона с помощью WiFi-маршрутизаторов
The quality of a wireless network depends essentially on the directional characteristics of the antennas, the most important of which are the amplitude radiation pattern (RP) and the frequency response (FR), which is understood as a change of the gain coefficient in the working frequency band.
