Embodiment Construction

[0015] The ultra-wideband cup-shaped monopole antenna of the present invention is composed of a coplanar waveguide 1 , a monopole antenna element 7 and a dielectric substrate 3 .

[0016] On one side of the dielectric substrate 3 is a coplanar waveguide 1 and a monopole antenna 7, and the other side has no metal layer; the monopole antenna element 7 is directly connected to the substrate integrated coplanar waveguide 1, and there are three circular holes on the antenna 4. There is a tuning stub 6 in the notch 5 on the top of the antenna, which is perpendicular to the antenna; the substrate integrated waveguide is located at the bottom of the antenna and directly connected to the antenna. The antenna structure is shown in Figure 1. The size of the dielectric substrate is 51×42×2 (L×W×H), the dimension unit is mm, and the antenna radiation unit is a semicircle with a radius of 15mm. The substrate of the antenna adopts a plate with a dielectric constant of 2.7, and the thickness ...

Abstract

The invention relates to a printing cup-shaped monopole antenna applied in ultra wide band communication. The antenna adopts a substrate integrated waveguide feed and plane printing technology and is suitable for ultra wide bands, multi-band frequency application occasions requiring to realize plane integration on the antenna and a system. The antenna comprises a radiating element (7), a metal ground plane (2), a medium substrate (3) and a coplanar waveguide feed part (1), wherein the radiating element (7) and the coplanar waveguide feed part (1) are arranged on the same side of the medium substrate (3); the thickness (8) of the medium substrate is 2 mm; the middle of the radiating element (7) is provided with three circular holes (4); the semicircular bottom end of the radiating element (7) is connected with the coplanar waveguide feed part (1); and the top end of the semicircular radiating element (7) is formed by a notch (5) and an open circuit short branch knot (6), wherein the other surface of the medium substrate is not provided with a metal plate. Compared with the traditional monopole antenna, the printing cup-shaped monopole antenna has low manufacture cost, can be integrated with a microstrip circuit and also has the characteristics of the ultra wide bands and the omnibearing characteristic.

Description

technical field [0001] The invention relates to a printed cup-type monopole antenna applied in ultra-wideband communication. The antenna adopts substrate-integrated waveguide feeding and planar printing technology, and is suitable for ultra-wideband, multi-frequency bands, and needs to achieve a plane between the antenna and the system. Integrated applications. Background technique [0002] Since UWB pulse radio technology was defined and accepted in the United States, it has aroused the research interest of many scholars. After years of development, the design of transceiver antennas in UWB communications is still a challenging subject. Ultra-wideband antennas need to work in a very wide frequency band, and at the same time require good time-domain characteristics, that is, the smallest pulse distortion response; broadband antennas also play an increasingly important role in modern wireless communication systems. Its appearance avoids the multi-band microstrip antenna des...
