Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a radiation regulation-based laminated patch antenna and communication equipment. Background technique [0002] With the vigorous development of mobile communications, more and more wireless terminal devices have entered people's lives. Wireless terminal devices are an important part of the Internet of Things. They transmit electromagnetic signals all the time for information exchange and intercommunication, and establish a world where everything is connected. Just like this, the space is filled with electromagnetic beams of various frequency bands, and there is serious electromagnetic interference between them. The concept of green communication came into being. [0003] Green communication refers to the new generation of communication concept of energy saving and emission reduction, reduction of environmental pollution, resource waste, and harm to human body and environm...
