Abstract

The invention discloses an ultra wideband planar antenna. The ultra wideband planar antenna comprises a dielectric layer, a radiation patch, a microstrip feeding line and a grounding part, wherein the radiation patch the microstrip feeding line are formed on one surface of the dielectric layer, the grounding part is formed on the other surface of the dielectric layer, the radiation patch comprises a first patch, a second patch and a third patch, the first patch comprises a first radiation segment, a second radiation segment and a third radiation segment, the first radiation segment and the second radiation segment are in parallel, extend along a first direction and are in rectangular shapes, the third radiation segment extends along a second direction, two ends of the third radiation segment are respectively connected with the first radiation segment and the third radiation segment, the second patch comprises a fourth radiation segment and a fifth radiation segment, the fourth radiation segment extends along the first direction, the fifth radiation segment extends along the second direction, the fourth radiation segment and the fifth radiation segment are in inverted L shapes, the third patch is arranged in a space encircled by the first patch and the second patch, and the microstrip feeding line is connected with the third patch. The antenna has the characteristics of ultra wide band, high gain and quasi omnidirectional performance, and can be applied to various different wireless communication environments.

Description

technical field [0001] The application belongs to the technical field of wireless communication, and in particular relates to an ultra-wideband planar antenna. Background technique [0002] With the development of the communication industry, people's requirements for communication equipment are getting higher and higher, and the antenna, as the receiving and transmitting end of the communication equipment, adapts to the development of the communication equipment. [0003] Microstrip antennas have attracted more and more attention because of their small size, light weight, low cost and easy fabrication. But narrow bandwidth is one of the main disadvantages of microstrip antennas. Contents of the invention [0004] The object of the present invention is to provide an ultra-wideband planar antenna to overcome the deficiencies in the prior art. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] The embodiment of ...
