Abstract

The invention provides a first antenna radiator, a second antenna radiator, a first power feed source, a second power feed source, a first metal piece and a filter. The first feed source and the firstantenna radiator form a first antenna with a working frequency band being a first frequency band; the second power feed and the second antenna radiator form a second antenna with a working frequencyband being a second frequency band; the first feed source, the first antenna radiator, the first metal piece and the filter form a third antenna with a working frequency band being a third frequency band; the second power feed source, the second antenna radiator, the first metal piece and the filter form a fourth antenna with a working frequency band being a fourth frequency band; the first frequency band is the same as the second frequency band, and the third frequency band is the same as the fourth frequency band; and the filter is used for filtering signals in the first frequency band and / or the second frequency band. The antenna device and the terminal device provided by the invention meet the isolation requirement and the bandwidth requirement of a multi-antenna system.

Description

technical field [0001] The present application relates to the field of electronic equipment, and more specifically, relates to an antenna module, an antenna device, and a terminal equipment. Background technique [0002] Due to the ever-increasing demand for transmission rates, multi-antenna systems have attracted increasing attention. However, the internal space of the communication device is very limited. If multiple antennas are to be built in a limited space, the interference problem between the antennas is particularly prominent. Therefore, the isolation between antennas becomes one of the factors that need to be considered when designing a multi-antenna system. [0003] In addition, antennas of the fifth-generation mobile communication technology (5th-Generation, 5G) need to cover three broadband (time division duplexing, TDD) frequency bands. In other words, bandwidth is also one of the factors to be considered when designing a multi-antenna system. [0004] There...
