Problems solved by technology

However, the above antennas all have the disadvantage of complex structure, which is not conducive to the current demand for simplification and easy integration of devices. In addition, the above antennas only realize the dual-frequency characteristics, and do not realize the radiation characteristics of the WIMAX frequency band.

Abstract

The invention provides a three-frequency coplanar waveguide fed antenna applied to WLAN / WIMAX, and relates to the field of antennas. The invention is a simple-structured three-frequency coplanar waveguide fed monopole antenna applied to WLAN / WIMAX , the tri-frequency coplanar waveguide-fed monopole antenna designed in the present invention, the ring antenna unit has a nested structure, and the size is small, which can greatly reduce the occupied space. The feeding structure adopts the coplanar waveguide feeding structure, and the radiation The unit is a monopole radiation patch. All metal patches of this structure are on the same side, which is easy to integrate and simple to manufacture. The dielectric substrate is made of FR4 material with a dielectric constant of 4.4, which is cheap and easy to purchase. The present invention has low production cost. It is easy to integrate and process, can be produced in batches, and has great practical application value.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a monopole antenna. Background technique [0002] With the rapid development of wireless communication technology, people's life and work have become more and more inseparable from the wireless local area network (WLAN). WLAN (2.4~2.4835GHz / 5.15~5.825GHz) uses wireless communication technology to transmit data. These data are no longer limited to voice and text information. Nowadays, video data transmission accounts for an increasing proportion. The table is liberated, so that users can exchange information anytime and anywhere. Worldwide Interconnection for Microwave Access Technology (WIMAX) is an emerging broadband wireless access technology, and the data transmission distance can reach up to 50Km. WIAMX (3.4-3.7GHz) also has the advantages of QoS guarantee, high transmission rate, and rich and diverse services. [0003] Scholars at home and abroad have done a lot of research on WLA...
