Abstract

The invention discloses a broadband antenna and a wireless communication device. The wireless communication device with an outer metal frame of the broadband antenna comprises a radiating body, a fixing point, a feed element and a parasitic radiating body. The radiating body is used for receiving and transmitting a radio-frequency signal and coupled to a grounding portion through the fixing point. The feed element is electrically connected between the radiating body and the grounding portion and used for feeding the radio-frequency signal to the radiating body. The parasitic radiating body is electrically connected to the grounding portion. A first distance is formed between the parasitic radiating body and the radiating body. The parasitic radiating body is one part of the outer metal frame. Coupling effect between the parasitic radiating body and the radiating body is generated due to the first distance so as to form a coupling antenna used for receiving and transmitting the radio-frequency signal.

Description

technical field [0001] The invention relates to a broadband antenna and a wireless communication device, in particular to a broadband antenna and a wireless communication device which use a metal frame as a parasitic radiator to increase the operating bandwidth and conform to the product structure. Background technique [0002] Antennas are used to transmit or receive radio waves to transmit or exchange radio signals. Generally, electronic products with wireless communication functions, such as notebook computers, personal digital assistants (Personal Digital Assistant), etc., usually access wireless networks through built-in antennas. With the evolution of wireless communication technology, the operating frequencies of different wireless communication systems may be different. Therefore, an ideal antenna should be able to cover frequency bands required by different wireless communication networks with a single antenna. [0003] Most of today's portable wireless communicati...
