Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] figure 1 It is a schematic structural diagram of the antenna of the present invention. As shown in the figure, the small planar multi-band antenna has three operating frequency bands, and is composed of a dielectric substrate of the antenna, a ground plane on the back of the substrate, a metal strip, and a radiation unit on the front of the substrate.

[0023] Specifically, the radiating element of this tri-band antenna includes a radius R 2 -R 1 A metal ring, a section of 50Ω microstrip feeder, and two U-shaped slots on the ring. The opening orientations of the two U-shaped grooves are consistent. The transverse length of the U-shaped groove is L 1 , the length of the two branches of the U-shaped groove is H 1 , the gap width of the U-shaped groove is W 1 ,Such as figure 1 (b) shown. On the other side of the substrate is com...

Abstract

The invention discloses a small type plane multiband antenna, and belongs to the technical field of wireless communication. The small type plane multiband antenna is composed of a dielectric substrate, a radiating element on the front face of the substrate, a ground plane on the back of the substrate and a metal belt; the radiating element is composed of a metal circular ring and a section of microstrip feeder, two U-shaped grooves are carved in the metal circular ring, and openings of the two U-shaped grooves face the same direction; The metal belt and the ground plane are arranged on the back face of the substrate, two H-shaped grooves are carved on the ground plane, and the two H-shaped grooves are the same in size. The antenna is provided with three working bands and has the advantages of being miniaturized, simple in structure, easy to produce and easy to integrate. The antenna has good application prospect in the field of wireless communication.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a small planar multi-band antenna. Background technique [0002] In recent years, in order to adapt to the rapid development of modern wireless communication technology, new wireless communication standards and technologies have been continuously proposed and applied. Wireless local area network (WLAN) uses wireless communication technology to transmit data, voice and video signals in the air, which can free users from fixed locations and exchange information anytime and anywhere. Worldwide Interoperability for Microwave Access (WiMAX) is one of the emerging broadband wireless access technologies that provides high-speed Internet-oriented connections. Wireless communication devices usually have multiple system modules at the same time and work in multiple frequency bands. As an important part of the communication terminal in the mobile communication system, the ant...
