Embodiment Construction

[0029] figure 1 It is a structural schematic diagram of the antenna of the present invention. In order to better describe the antenna structure of the present invention, figure 1 Use perspective drawing. Such as figure 1 As shown, the antenna of the present invention includes a first dielectric substrate 1 and a second dielectric substrate 2 covering the first dielectric substrate 1 . A metal sheet 10 and a feeder 11 arranged around the metal sheet 10 are arranged on the first dielectric substrate 1 , and an asymmetric first microgroove structure 100 and a second microgroove structure 200 are hollowed out on the metal sheet 10 . The asymmetry here refers to the difference in pattern, size and / or spatial position between the first microgroove structure 100 and the second microgroove structure 200, resulting in the resonance between the first microgroove structure 100 and the second microgroove structure 200 The frequency is different.

[0030] The feeder line 11 is arrange...

Abstract

The invention discloses an antenna which comprises a first dielectric substrate and a second dielectric substrate, wherein a metal sheet and a feeder that surrounds the metal sheet and is fed in the metal sheet in a coupled mode are arranged on the first dielectric substrate; the first dielectric substrate is covered with the second dielectric substrate; and at least one first microgroove structure and one second microgroove structure that are unsymmetrical are hollowed on the metal sheet to allow the antenna to have at least two different resonance frequency bands. According to the antenna, the first dielectric substrate is covered with the second dielectric substrate, so that the miniaturization and the high performance of the antenna can be ensured when the antenna works at a low frequency; the two unsymmetrical microgroove structures are arranged on the metal sheet, so that the antenna at least has two resonance frequency bands; and multiple modes can be achieved easily. In addition, the invention further discloses an MIMO (multiple input multiple output) antenna provided with the antennas, and the MIMO antenna has high isolation.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an antenna and a MIMO antenna with the 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 lines are used to meet the multi-mode radiation ...
