EFFECTIVE AREA AND DIRECTIONAL PATTERNS OF ANTENNA ARRAY OPERATING IN ULTRA WIDEBAND SIGNALS RECEIVING MODE

The relations for effective area calculation of arbitrary antennaarray which receives ultra wideband signal are obtained. The effectivearea is presented as function of direction of electromagneticwave arrival and signal bandwidth. The relations obtained areused for numerical analysis of effective ar...

Получены соотношения для расчета эффективной поверхности (ЭП) произвольной антенной решетки, принимающей сверхширокополосный (СШП) сигнал, которая представлена как функция от направления прихода электромагнитной волны и ширины спектра сигнала. Полученные соотношения использованы для численного анализа ЭП и диаграмм направленности (ДН) плоской антенной решетки из 5×5 элементов над экраном, которая может служить прототипом секции фазированной антенной решетки радиотелескопа декаметрового диапазона волн. Приведены ДН этой решетки, рассчитанные для плоскостей E и H. Показано, что максимальная ЭП антенной решетки, принимающей СШП сигнал, близка по величине к ЭП на центральной частоте рабочей полосы, а ее угловая зависимость в результатечастотного усреднения приобретает сглаженную форму, безлепестковую вне области главного лепестка с заметно уменьшенным уровнем.
