Problems solved by technology

Although such a design idea can achieve good isolation to a certain extent, the resulting MIMO antenna structure is generally more complex and takes up a large space, and the introduction of decoupling methods often reduces the performance of the antenna itself to a certain extent.

Abstract

The present application provides an antenna device and an electronic device. The antenna device comprises a first antenna radiator and a second antenna radiator, wherein the first antenna radiator comprises a first antenna side radiator on a first side of the electronic device and a first antenna bottom edge radiator located on a metal ground plane of the electronic device; the first antenna sideradiator comprises a first feed port; the first antenna bottom edge radiator comprises a second feed port; the two feed ports have different operating frequencies; the second antenna radiator comprises a second antenna side radiator located on a second side of the electronic device and a second antenna bottom edge radiator located on the metal ground plane; the second antenna side radiator comprises a third feed port; the second antenna bottom edge radiator comprises a fourth feed port; and the two feed ports have different working frequencies; the two side radiators are connected through a metal wire at the junction of the first side and the second side; the two bottom edge radiators are separated from each other and perpendicular to each other, so that a compact layout of the antenna canbe realized; also, the isolation degree between the antennas can be ensured.

Description

technical field [0001] The present application relates to the field of antennas, and more particularly, to an antenna device and electronic equipment. Background technique [0002] Multiple-Input Multiple-Output (MIMO) antenna technology is one of the main core technologies of MIMO wireless communication technology. The traditional Single-Input Single-Output (SISO) antenna system has a large channel capacity. It has an unbreakable bottleneck - the limitation of Shannon's capacity. However, under the condition of no size limitation, the more the number of antennas, the system throughput will increase exponentially with the number of antennas. With the maturity of 4G communication, 4.5G and 5G are being extensively studied. There is no doubt that the channel capacity indicator will become one of the core concerns of 5G communications. The MIMO technology based on multiple antennas can provide greater channel capacity without expanding the frequency band, and the channel cap...
