Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the ...

Abstract

The invention discloses a dipole filter antenna, which comprises a dielectric substrate, and an input port feeder line and a dipole antenna unit, which are arranged on a first surface of the dielectric substrate. The input port feeder line is connected with a feed source; and a second surface of the dielectric substrate is provided with a metal ground, wherein the metal ground is provided with a coupling groove line. The invention also discloses electronic equipment. According to the dipole filter antenna based on the input port feeder line and the coupling groove line, differential feed is provided for the dipole antenna through broadside coupling between the input port feeder line and the coupling groove line, thereby realizing integrated design of a Barron filter and the dipole antenna.The dipole filter antenna is simple in structure and has higher antenna gain.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dipole filter antenna and an electronic device. Background technique [0002] With the development of wireless communication technology, radio frequency systems are developing in the direction of miniaturization, integration, and multi-function. The filter antenna is an integration of two important components, the antenna and the filter. It can not only reduce the size of the system, but also improve the selectivity of the working frequency band and the out-of-band suppression ability on the basis of achieving good radiation characteristics. [0003] When cascading filters in the antenna, it is usually chosen to load the filter on the feeder. This approach generally increases the size of the antenna and increases feed loss. Since the antenna can act not only as a radiating unit but also as the last order of the entire resonant network, the antenna can be designed to have bot...
