摘要： An antenna apparatus is provided. The antenna apparatus includes an antenna module and the antenna radome. The antenna module is configured to receive/emit a first radio frequency (RF) signal in a first preset frequency band in a first preset direction range and receive/emit a second RF signal in a second preset frequency band in a second preset direction range, where the first preset frequency band is lower than the second preset frequency band, and the first preset direction range and the second preset direction range have an overlapped region. An antenna radome is spaced apart from the antenna module and includes a substrate and a resonant structure carried on the substrate, where the resonant structure is at least partially located in the overlapped region. The resonant structure at least has in-phase reflection characteristics to the first RF signal and in-phase reflection characteristics to the second RF signal.

摘要： An antenna coupling element includes a first coil connected to a first radiating element and a feeder circuit and a second coil connected to a second radiating element and electromagnetically coupled to the first coil. The first and second coils have a relationship in which a direction of a magnetic field generated in the first coil when a current flows from the first coil toward the first radiating element and a direction of a magnetic field generated in the second coil when a current flows from the second coil toward the second radiating element are opposite to each other. The first and second coils are set such that a resonant frequency of a fundamental wave of the second radiating element with a transformer defined by the first coil and the second coil is lower than a resonant frequency of a fundamental wave of the first radiating element.

摘要： A high-isolation terminal antenna system, to provide improved radiation performance and isolation by combining current loop antennas and/or magnetic loop antennas with different position features. The terminal antenna system includes a first antenna and a second antenna, and the first antenna and the second antenna include at least one current loop antenna or magnetic loop antenna. When the current loop antenna operates, a uniform magnetic field is distributed between a radiating element of the current loop antenna and a reference ground. When the magnetic loop antenna operates, a uniform electric field is distributed between a radiating element of the magnetic loop antenna and the reference ground. The first antenna and the second antenna are arranged at a same edge of an electronic device, or are arranged at two opposite edges of the electronic device.

摘要： This application provides a wireless data terminal and a wireless data terminal control system. The wireless data terminal includes a housing, a drive assembly, a first antenna assembly, and a second antenna assembly. The drive assembly can drive the first antenna assembly and the second antenna assembly to extend or retract to move in different directions between a first location and a second location. When the wireless data terminal does not need to be used or high isolation between antennas is not required, the drive assembly may drive the antenna assembly to retract to the first location, so that a volume occupied by the wireless data terminal can be reduced while an antenna isolation requirement is met. When high isolation between the antennas is required, the drive assembly may drive the antenna assembly to extend to the second location, so that isolation between the antennas is increased.
