Antenna with special-shaped radiator and equipment

Abstract

The invention discloses an antenna with a special-shaped radiator. A long-strip-shaped clearance area is arranged on the base plate. The strip-shaped clearance area is arranged at the frame of the substrate. According to the invention, the grounding point and the feed point are arranged at one end, close to the center of the substrate, of the long-strip-shaped clearance area in the length direction; and because the length of the short end is short, based on the setting mode, the radio frequency module can be arranged close to the substrate frame connected with the short end, more complete space is reserved for other devices on the substrate, the layout of the other devices is facilitated, the radio frequency wiring is not U-shaped or U-shaped, the required radio frequency wiring is shorter, the probability of being interfered by other signal wiring or power supply wiring is reduced, and meanwhile, the insertion loss of the radio frequency wiring is also reduced. The invention further discloses equipment which has the same effect as the antenna.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna and equipment with a special-shaped radiator. Background technique [0002] With the development of 5G communication technology, more and more devices such as Internet of Things devices, smart wearable devices, and security monitoring devices are being used. These devices have higher and higher requirements on their own volume, and require the volume to be as small as possible, which also makes the antenna design in the device more and more difficult. The antenna is set on the clear area of ​​the substrate, and usually includes a radiator, a feed point conductor, a feed point, and a ground point. When the antenna in the prior art sets the feed point and the ground point, the feed point and the ground point are usually set near the substrate. In this case, if the RF module and the RF traces are also placed at the center of the substrate, although this method can ...

These devices have higher and higher requirements for their own volume, requiring the volume to be as small as possible, which also makes the antenna design in the device more and more difficult

The antenna is set on the clear area of ​​the substrate, and usually includes a radiator, a feed point conductor, a feed point, and a ground point. When the antenna in the prior art sets the feed point and the ground point, the feed point and the ground point are usually set near the substrate. In this case, if the RF module and the RF traces are also placed at the center of the substrate, although this method can ensure the isolation of the RF and the length of the RF traces is relatively short, it leaves space for the substrate on the substrate. The complete space of other devices is significantly reduced, which is not convenient for the layout of other devices on the substrate; if the RF module and RF traces are placed close to the frame, this method can leave more complete space for other devices on the substrate , but it will make the RF trace a "U" shape or " "shaped loop, which causes the distance between the input and output ends of the RF trace to be relatively close, which increases the coupling between signals and affects the isolation of the RF signal; and the length of the required RF trace is longer, which increases the RF trace. The insertion loss of the line (including skin loss and dielectric loss) also increases the difficulty of routing between radio frequency signals and other signals
