Embodiment Construction

[0033] see figure 1 , figure 1 It is an area setting diagram of the PCB of an embodiment of the coupling antenna 10 of the present invention.

[0034] In this embodiment, the coupling antenna 10 is disposed on the substrate A of the communication device, and is used for transmitting radio electromagnetic wave signals and suppressing the influence of the radio electromagnetic wave signals emitted by the antenna on other radio frequency components. For example, suppress the radio frequency interference of the electromagnetic waves emitted by it on the connectors and radio frequency modules on the substrate A.

[0035] The substrate A is a commonly used printed circuit board (PCB, Printed Circuit Board), and its electrical characteristics can be selected according to the frequency of the signal to be suppressed. For example, choose the most commonly used glass fiber epoxy resin copper clad laminate (FR-4 copper clad laminate) and other multilayer boards. In this embodiment, if...

Abstract

Provided is a coupling antenna, which is disposed on a substrate, and comprises a first antenna branch, a second antenna branch and a coupling part. The first antenna branch is disposed at a first layer of the substrate, and the second antenna branch is disposed at the first layer of the substrate and does not overlap with the first antenna branch. The coupling part is disposed at a second layer of the substrate, and a gap is disposed between the coupling part and the first antenna branch, and between the coupling part and the second antenna branch. The coupling part partially overlaps with the projection of the first antenna branch on the second layer and the projection of the second antenna branch on the second layer. The invention also provides a communication device using the above coupling antenna. The invention is advantageous in that the coupling antenna is small in volume, and strong in antenna usefulness in limited space; the noise interference of the antenna to other elementsin the substrate can be reduced, and the product design of being light, thin, short and small can be realized.

Description

technical field [0001] The invention relates to an antenna, in particular to a coupling antenna and a communication device. Background technique [0002] In daily life, antennas are widely used. In some antenna designs, the designer will set some antennas that can extend outwards to form a radiation pattern of the coupled antennas, thereby improving the wireless communication performance of the product. However, in the above-mentioned antenna design, the antenna often transmits the wireless electromagnetic wave signal of the antenna through a coaxial cable, and the volume of the antenna is often too large, and the antenna is a part extending outward from the PCB board, resulting in an excessively large product design. . The above-mentioned design is not conducive to reducing the size of the antenna and reducing the size of the product. At the same time, reducing the interference of antenna noise to the radio frequency components in the product is also a major research and...
