Abstract

Настоящее изобретение относится к беспроводному передающему устройству. Беспроводное передающее устройство содержит множество передающих антенн, модуль сдвига фаз, который добавляет сдвиг фаз к сигналам, которые соответственно поступают на множество передающих антенн. При этом модуль сдвига фаз добавляет первый сдвиг фаз к сигналам для управления максимальным временем задержки между множеством передающих антенн и вторым сдвигом фаз для управления фазами антенн, произвольно выбранных из множества передающих антенн.
