Example Embodiment

[0045] Example 1

[0046]It can be seen from the top view and side view of FIG. 1 that the radio frequency module 2 is coupled to the surface of the dielectric substrate 1 and is used to convert signals generated by various electronic components on the PCB into radio frequency signals. In this embodiment, the feed line 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 in the long axis direction 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 ground plane 3 is coupled to the other surface of the dielectric substrate 1 where the radio frequency module 2 is located, and its size is about the same as that of the substrate, and it is usually made of conductive material (such as a metal plate) for grounding. The X-shaped coup...

Example Embodiment

[0053] Example 2

[0054] Figure 2 shows three views of the slot antenna of the present invention. This embodiment is similar to the above-mentioned embodiment, so 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 a figure-eight coupling slot 9.

[0055] From the top view and side view of FIG. 2, it can be seen that this embodiment is characterized in that the figure-eight coupling slot 9 is on the ground plane 3. From the front view of FIG. 2, it can be seen that the feeder 4 roughly passes through the intersection of the figure-eight coupling slot 9. The feeder 4 is usually a signal transmission line for transmitting communication signals. The radiating plate 5 is connected to the inside of the dielectric housing 7 and has an area approximately larger than the area of ​​the figure-eight coupling slot 9 and is at the position of the figure-eight coupling slot 9. The radiation plat...

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.
