Abstract

The invention provides a dual-frequency common-caliber phased-array antenna, a communication device and a system. The antenna comprises a radiation layer and a feed layer which are sequentially formed by multiple layers of dielectric substrates from top to bottom. Each Ku frequency band radiation patch and three Ka frequency band radiation patches in the radiation layer randomly form a matrix type common-caliber phased array antenna unit so as to form a radiation patch antenna array; the feed layer is provided with a micro-strip feed network, and energy of the feed layer is coupled to the radiation patch through the micro-strip feed network and a coupling gap; and each Ku frequency band radiation patch and three Ka frequency band radiation patches form a matrix type phased array antenna unit at will so that a radiation patch antenna array is formed in the radiation layer. According to the ka random array arrangement mode of the phased array, the phased array antenna can obtain a larger array spacing, and meanwhile, grating lobes cannot be generated under a large scanning angle; and the application of a large-angle scanning phased array system with limited size and weight can be well met.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dual-frequency common-aperture phased array antenna, a communication device and a system. Background technique [0002] In the ever-changing field of information technology, wireless communication technology has become an indispensable means of information exchange, and its application fields continue to expand. It is one of the fastest-growing engineering technologies today. Wireless communication technologies (for example, phased array antennas) have not only been widely used in military fields such as missile guidance, microwave remote sensing, satellite and radar communications, but also in civilian fields such as the Internet of Things, mobile communications, and wireless local area networks. and widely used. [0003] At present, in order to reduce the volume of the system and the RCS (Radar Cross Section) of the phased array antenna, it is urgent to reduce...
