Problems solved by technology

Although the quarter-wavelength antenna is less affected by the environment, its wiring length is almost twice that of the quarter-wavelength antenna under the same environment, which requires too much space for the antenna.

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with accompanying drawing, but not as limiting the present invention:

[0031] like figure 1 As shown, this embodiment includes: a reference ground plane 1, a dielectric layer 2, a grounded conductive antenna element 3, a conductive antenna element 4 connected to signal feed, the grounded conductive antenna element 3 and the connected signal feed A coupling gap is formed between the incoming conductive antenna elements 4, and the grounded conductive antenna element 3 is not connected to the conductive antenna element 4 connected to the signal feed.

[0032] The reference ground plane 1 in this embodiment may be a PCB board of the mobile terminal, or may be a conductive device serving as a reference ground of the mobile terminal.

[0033] The reference ground plane 1 in this embodiment extends to or does not extend below the grounded conductive antenna element and the conductive antenna element conne...

Abstract

The invention discloses a mobile terminal antenna with aperture coupling feed, and the mobile terminal antenna comprises a reference ground plane, a dielectric layer, a grounded conductive antenna element and a conductive antenna element connected with a signal feeder, wherein a coupled aperture is formed between the grounded conductive antenna element and the conductive antenna element connected with the signal feeder; and the grounded conductive antenna element is not connected with the conductive antenna element connected with the signal feeder. The mobile terminal antenna can be used for reducing the influence of environment on the antenna under the condition that the volume of the antenna is reduced, and is suitable for an ultrathin mobile phone; and the length of a conductive antenna element body is reduced, so that the material needed by the production is reduced, and the production cost is lowered.

Description

(1) Technical field: [0001] The invention belongs to the field of antennas for electronic mobile terminals, and relates to a mobile terminal antenna for slot coupling feeding. (two) background technology: [0002] The antennas currently on the market mainly include the following types: [0003] a) Antenna feeds with double feed pins or multiple feed pins used in ordinary mobile terminals are all direct-connected feeds, that is, the grounded conductive antenna element is directly connected to the conductive antenna element connected to the signal feed. [0004] b) Slot coupling is widely used in mobile terminal antennas, but they are all used to increase resonance or expand bandwidth, such as FICA antennas of motorcycle companies or conventional slot antennas. [0005] c) There is a way to apply slot feeding in the microstrip antenna, but it is not applied to the antenna of the mobile terminal. The current mobile terminals require miniaturization, and the main board and the...
