Embodiment Construction

[0028] The present invention will be further explained below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, an ultra-wideband planar monopole antenna includes: a dielectric substrate 5 , a monopole radiation patch and a lumped device arranged on the surface of the dielectric substrate 5 , and a ground plate 7 arranged at one end of the dielectric substrate 5 .

[0030] The dielectric substrate 5 is a Rogers RT5880 dielectric board with a dielectric constant of 2.2, with a width of 12 cm and a height of 35 cm. The dielectric substrate 5 and the ground plate 7 are fixed by an L-shaped stand piece 8 . The monopole radiating patch is a copper-clad structure on one side of the dielectric substrate, with an overall height of 34 cm and a width of 12 cm, including the monopole antenna main body 6 and the antenna top loading. Wherein, the main body 6 of the monopole antenna is composed of three sections of copper-clad patches with triangular cut co...

Abstract

The invention discloses an ultra-broadband planar monopole antenna, which comprises: a dielectric substrate, a monopole radiation patch, a lumped device and a grounding plate. A monopole radiating patch consists of a monopole antenna body and a top loading. The part of the monopole radiation patch close to the ground plate adopts a triangular cut corner, which is mainly used for impedance matching of the high frequency part. The lumped element loaded on the main body of the antenna is mainly used to reduce the working frequency band of the antenna and smooth the gain of the antenna in the whole frequency band; multiple rectangular open-circuit branches are loaded on the top of the monopole to increase the capacitance between the antenna and the floor, and further reduce the working frequency band of the antenna . The invention effectively reduces the size of the antenna while maintaining excellent ultra-broadband characteristics by loading lumped elements and adding open-circuit stubs to the ground, thereby facilitating the application of the antenna in the monitoring field.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to an ultra-wideband (UWB) antenna. Background technique [0002] With the rapid development of radio technology, the demand for radio frequency resources is increasing, and radio monitoring and management are facing more challenges. As an important part of radio monitoring, the monitoring system puts forward higher and higher requirements for the wide frequency band and high gain of the front-end monitoring antenna. At the same time, with the continuous development of low-altitude electronic equipment, such as low-altitude flying drone technology, handheld monitoring equipment is facing greater market demand. Traditional monitoring antennas can no longer meet the needs of the application. Therefore, it is particularly urgent to design a monitoring antenna with wider frequency band, higher gain, smaller size and longer monitoring distance. At present, the antenna forms used in m...
