Wireless universal three-frequency-band monopole antenna and wireless communication device

Abstract

The invention relates to the field of wireless communication, and discloses a wireless universal three-frequency-band monopole antenna and a wireless communication device. The antenna comprises a dielectric substrate, a radiation patch formed on the surface of the dielectric substrate, a grounding layer formed on the surface of the side, away from the radiation patch, of the dielectric substrate, and a feed port penetrating through the dielectric substrate and used for connecting the radiation patch and the grounding layer. The radiation patch is provided with a first antenna unit, a second antenna unit and a third antenna unit, and the first antenna unit, the second antenna unit and the third antenna unit are all electrically connected with the feed port. The three antenna units of the wireless universal three-frequency-band monopole antenna can make resonance responses in different frequency band ranges, namely, the wireless universal three-frequency-band monopole antenna can make resonance responses in multiple working frequency bands at the same time, the function is powerful, and the application range is wide. The antenna unit is compact and simple in structure, and overcomes the defect that the working frequency of the center of the traditional monopole antenna is single.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless universal tri-band monopole antenna and a wireless communication device. Background technique [0002] With the continuous development of wireless communication technology, Wireless Local Area Networks (WLAN) and Worldwide Interoperability for Microwave Access (WIMAX) have been widely used in people's daily life. Specifically, WLAN is a wireless local area network based on the IEEE802.11 standard, which allows the transmission of voice, video and other data in the 2.4GHz-2.484GHz and 5.725GHz-5.825GHz frequency bands, and is used in many offices, restaurants, hotels and squares. place. WIMAX is based on the IEEE802.16 standard and mainly provides high-speed wireless network connections in the 2.5GHz-2.69GHz, 3.4GHz-3.69GHz and 5.25GHz-5.85GHz frequency bands, which can solve the "last mile" wireless broadband for enterprises and families.
