Embodiment Construction

[0029] Such as figure 1 as shown, figure 1 It is a schematic diagram of the structure of the asymmetric antenna of the present invention. figure 1 Among them, the asymmetric antenna of the present invention includes a feeder 1 and a metal sheet 2 . At least the asymmetric first micro-groove structure 100 and the second micro-groove structure 200 are engraved on the metal sheet 2, so that the asymmetric antenna has at least two different resonant frequencies. The asymmetry here means that the pattern, size and / or spatial position of the first microgroove structure 100 and the second microgroove structure 200 are different, and these differences lead to the resonance of the first microgroove structure 100 and the second microgroove structure 200 The frequency bands are different.

[0030] The feeder 1 is partly arranged around the metal sheet 2 to couple and feed the metal sheet 2 . The feeder 1 couples and feeds the metal sheet 2 by setting a short-circuit point to connect ...

Abstract

The invention discloses an asymmetric antenna, which comprises a feeder line and a metal sheet. The feeder line feeds signals in the metal sheet in a coupling way. At least a first micro-channel structure and a second micro-channel structure are asymmetrically hollowed in the metal sheet, so that the antenna has at least two different resonance frequency bands. According to the asymmetric antenna, at least the first and second micro-channel structures are asymmetrically hollowed in the metal sheet, so that a plurality of resonance points can be easily produced, and are difficult to counteract, and multimode resonance can be easily realized. In addition, the invention also discloses a multiple input multiple output (MIMO) antenna comprising the asymmetric antenna. The MIMO antenna is high in isolation.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more specifically, relates to an asymmetric antenna and a MIMO antenna with the asymmetric antenna. Background technique [0002] In traditional antenna design, when problems such as small antenna space, low operating frequency, and multi-mode operation are encountered, the performance of the antenna will be greatly restricted by the size of the antenna. The electrical length of the antenna corresponding to the reduction of the volume of the antenna will also be affected, and the radiation efficiency and operating frequency of the antenna will change. Traditional dipole antennas and PIFA antennas are powerless when faced with the problems of small size and broadband in existing communication terminals, and the design is extremely difficult and ultimately cannot meet the requirements of use. In the design of traditional antennas in the low frequency band, only external matching l...
