Problems solved by technology

However, the frequency bands of this antenna are mutually restricted, it is difficult to achieve independent design, it is not easy to adjust in actual engineering, and the size of the antenna is relatively large
In addition, Andrea Michel et al. designed a new type of broadband microstrip antenna in 2016, printing multiple monopole antennas on the same compact dielectric substrate, using microstrip line feed, but its size is large , and cannot be flexibly designed according to requirements

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] to combine Figure 1 to Figure 4 , the antenna of the present invention mainly includes a dielectric substrate 106, an asymmetric coplanar line feeding transmission line 102, a ground plane 101, a ring radiating unit 103, a double U-shaped radiating unit 104 and a monopole radiating unit. Both the double U-shaped radiating unit 104 and the monopole radiating unit are connected to the annular radiating unit, and are indirectly fed through the annular radiating unit, and the monopole radiating unit is composed of a vertical radiating unit 1051 and a bent radiating unit 1052 (only this an embodiment of the invention). By adjusting the size of each radiating element, the coupling between the monopole radiating element and the double U-shaped radiating element, and the coupling gap between the annular radiating element and the grou...

Abstract

The invention provides a miniaturized multi-resonance antenna, which includes a dielectric substrate, a ring-shaped radiation unit arranged on the dielectric substrate, an asymmetric coplanar line feeding transmission line, a split structure radiation unit and a monopole embedded in the ring-shaped radiation unit The radiating unit, the half ground plane set on the dielectric substrate, the double U-shaped radiating unit and the monopole radiating unit are all connected to the annular radiating unit, the asymmetric coplanar line feeding transmission line is connected to the inner conductor of the SMA, and the outer conductor of the SMA The conductor is connected to the ground plane. The present invention is a miniaturized multi-resonant antenna, which adopts an asymmetrical coplanar line feed structure, radiating unit indirect feeding and multi-radiating unit fusion design, and achieves the effect of miniaturized design, and each radiating unit can be independently designed, which is convenient for realization Multi-band design.

Description

technical field [0001] The invention relates to an antenna structure, in particular to a miniaturized multi-resonance antenna. Background technique [0002] In recent years, the rapid development of wireless communication technology has been deeply rooted in the hearts of users, which has brought great convenience to our daily life. In an instant, the whole earth has become a global village, making people more and more dependent on wireless communication technology. getting stronger. From the transmission of text and voice to the current high-definition image transmission, the development of wireless communication is changing with each passing day, and the requirements for transmission rate and transmission bandwidth are also getting higher and higher. Especially in recent years, the rapid development of WiFi technology seems to make people unable to leave the high-speed transmission of WiFi. In order to meet the needs of users, WiFi usually works in two frequency bands. A...
