Title:
ARRAY ANTENNA AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/082959
Kind Code:
A1
Abstract:
Provided in the present application are an array antenna and a mobile terminal. In the present application, by providing multiple columns of array elements to increase the number of array elements, the maximum gain reduction of an array antenna in a maximum scanning region is reduced. Furthermore, by configuring each feed network to support a 28 GHz frequency band and a 39 GHz frequency band, 2*2 MIMO signal differentiated communication for each array element is achieved, so that the array antenna supporting a dual-frequency dual-polarized signal is achieved. Meanwhile, the antenna array can be automatically adjusted according to signal strength to reduce input power, thereby increasing the operating energy efficiency of the system and dynamically adjusting the operating temperature of a chip.
