Abstract

The invention relates to a triple-frequency-band antenna used in WLAN and WiMAX and belongs to the technical field of wireless communication. The triple-frequency-band antenna comprises a bottom first microstrip branch structure (1), a left second microstrip branch structure (2, 3), an intermediate microstrip branch structure (4), a right fourth microstrip branch structure (5-7), a microstrip feed line (8), a comb-shaped parasitic unit (9-12), a common-ground structure (13-18), and a dielectric slab (19). The triple-frequency-band antenna is characterized in that (a), a basic radiation unit is formed by the four microstrip branch structures mentioned above and is directly connected with the microstrip feed line (8); (b), a gap is arranged between the microstrip feed line (8) and the common-ground structure such that coplanar waveguide feed is formed; and (c), the dielectric slab uses FR4 dielectric material. The triple-frequency-band antenna has advantages of compact structure, easy integration, simple processing, multiple frequency bands, good tenability, and a stable directional diagram, and may simultaneously satisfy requirements of WLAN and WiMAX systems.

Description

technical field [0001] The invention relates to a three-band antenna applied to WLAN and WiMAX, belonging to the technical field of wireless communication. Background technique [0002] With the rapid development of modern wireless communication technologies, wireless local area networks (Wireless Local Area Networks, WLAN) have been widely used. WLAN uses wireless communication technology to transmit data, voice and video signals in the air, so that users can exchange information anytime and anywhere. Worldwide Interoperability for Microwave Access (WiMAX) is an emerging broadband wireless access technology that can provide high-speed Internet-oriented connections, and the data transmission distance can reach up to 50 kilometers. The current WLAN mainly works in 2.4 GHz (2.4-2.484 GHz), 5.2 GHz (5.15-5.35 GHz), 5.8 GHz (5.725-5.825 GHz). For WiMAX, there is currently no unified frequency division standard in various countries. Currently, frequency divisions in various cou...
