Problems solved by technology

[0008] (2) The above-mentioned antenna is usually mounted directly on the chassis, and the cable or adapter is used to connect the antenna to the main PCB board; therefore, there will be signal transmission loss (cable loss) on the cable. ), cable connection is not reliable (non-reliability), installation configuration or troubleshooting (trouble-shooting) are more difficult and other shortcomings
[0009] (3) For the antenna connected to the outside of the casing, the antenna is usually connected to the main PCB board through a cable or an adapter passing through the casing, which may cause signal loss or surface irregularities.
[0010] (4) For the antenna installed in an independent accessory (standalone) outside the casing, usually a cable or adapter passing through the casing is used to connect the antenna to the main PCB board, which will cause signal loss and require Higher mounting knowledge

Embodiment 1

[0046]As can be seen from the top view and side view of FIG. 1 , the radio frequency module 2 is coupled on the surface of the dielectric substrate 1 for converting signals generated by various electronic components on the PCB into radio frequency signals. In this embodiment, the feeder 4 is coupled to the surface of the dielectric substrate 1 on the same side as the radio frequency module 2 , one end of which is connected to the radio frequency module 2 , and extends toward a long axis substantially parallel to the dielectric substrate 1 . The feeder 4 usually also includes a stub, and the feeder is used to feed signals to the radio frequency module 2 .

[0047] The above-mentioned ground plane 3 is coupled on the other surface of the dielectric substrate 1 where the above-mentioned radio frequency module 2 is located, its size is about the same as the above-mentioned substrate, and it is usually made of conductive material (such as a metal plate) for grounding. An X-shaped c...

Embodiment 2

[0054] Figure 2 shows three views of the slot antenna of the present invention. This embodiment is similar to the above embodiment, so the details of the same structure will not be described in detail. The antenna structure includes a dielectric substrate 1 , a ground plane 3 , a radiation plate 5 and an 8-shaped coupling slot 9 .

[0055] As can be seen from the top view and side view of FIG. 2 , this embodiment is characterized in that the figure-eight coupling slot 9 is on the ground plane 3 . It can be seen from the front view of FIG. 2 that the feeder 4 roughly passes through the intersection point of the figure-eight coupling slot 9 . The feeder 4 is usually a signal transmission line for transmitting communication signals. The radiation plate 5 is connected to the inner side of the dielectric housing 7 , and its area is about larger than that of the figure-eight coupling slot 9 , and is located at the position of the figure-eight coupling slot 9 . The radiation plate ...

Abstract

The invention provides a hand-held communication device provide with a coupling slot antenna module, belonging to the communication field. The coupling slot antenna module mainly comprises a dielectric basal plate, a radio frequency module, a grounding plane, a resonance cavity and a radiation plate. A feed line and a branch line of the communication device are coupled on the surface of the dielectric basal plate and extended along the direction which is slightly parallel to the long edge of the dielectric basal plate. The grounding plane is coupled on the other surface of the dielectric basal plate and has a coupling slit structure, wherein, a cross point of the coupling slits is positioned on a position which the feed line and the branch line pass through. An air layer is arranged between the radiation plate and the grounding plane, the radiation plate is parallel to the grounding plane at the coupling slits.

Description

technical field [0001] The invention relates to a palm-type communication device, in particular to a palm-type communication device with a coupling slot antenna module. Background technique [0002] Due to the development of science and technology and the advancement of communication technology, wired networks have been unable to meet people's needs for network convenience.
