Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. A specific embodiment of the present invention is as figure 1 As shown, in the embodiment of the method of implementing the patch antenna broadband operation by using the coplanar terminal of the present invention, the patch antenna loaded by the coplanar terminal consists of two parts: the vibrator patch 1 and the coplanar terminal 2 . The antenna is a double-layer microstrip plate structure with a volume of 15*15*3mm 3 . The vibrator patch and the coplanar terminal are located on the same metal layer, and a metal back plate is provided on the other metal layer of the dielectric board. The intermediate dielectric substrate is made of FR-43 material, with a relative permittivity of 4.3 and a relative permeability of 1.0, the loss tangent is 0.015. The antenna is fed through a back-feed structure, that is, the inner conductor 3 of the SMA coaxi...

Abstract

The invention discloses a method for realizing broadband work of a patch antenna by using a coplanar terminal. According to the method, through the design of a coplanar terminal structure, the radiation current of the antenna is controlled, and then broadband matching of radiation impedance is achieved. Compared with a traditional patch antenna, the method has the advantages that the working bandwidth of the antenna is remarkably improved; and compared with broadband antennas in other forms, the method has the advantages of low profile, low cost, small size, light weight, easiness in processing and integration and the like, and the radiation performance of the antenna has the orientation characteristic consistent with that of a traditional patch antenna. The coplanar terminal loaded patch antenna designed based on the method is composed of an oscillator patch and the coplanar terminal, and has the characteristics of broadband, directional radiation and multi-polarization radiation.

Description

technical field [0001] The invention relates to the field of antennas (H05B6 / 72), in particular to a method for realizing broadband work of a patch antenna by using a coplanar terminal. Background technique [0002] Antenna technology is an important topic in the fields of communication and energy, which is used to receive and radiate electromagnetic waves. Since the 1980s, patch antennas have become the mainstream implementation form of antennas due to their advantages such as low profile, low cost, easy processing, directional radiation, and easy array work. In the research of patch antennas, there has always been a limitation that the antenna cannot work in broadband. This has limited the application environment of the patch antenna for a long time. With the rapid development of communication technology and other related fields, especially in high-speed antenna systems such as 5G, the demand for broadband patch antennas is increasing day by day. In related antenna rese...
