Description
Technical Field
The invention relates to the field of wireless equipment communication, in particular to a communication device capable of switching an external antenna according to actual conditions and a manufacturing method thereof.
Background
An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa, and is therefore a component of a radio device that emits or receives electromagnetic waves. Radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and other engineering systems, which use electromagnetic waves to transmit information, all rely on antennas to work. In addition, in the case of electromagnetic waves for energy transmission, non-signal energy radiation also requires the use of antennas. The common antennas are reversible, i.e., the same pair of antennas can be used as both the transmitting and receiving antennas.
For many wireless terminal products, the tuning of the wireless performance of the whole wireless terminal product is not limited to the design of the antenna unit, but is limited to the 'visible' environment reserved for the antenna by factors such as product ID, structure stacking, material and the like, and the 'invisible' environment such as electromagnetic interference generated by other parts in the product. To a certain extent, the environment of the antenna plays a decisive role in the wireless performance of the whole product.
Generally, the height of the antenna from the main board needs to be at least 8mm or more, and under extreme environments, the height needs to be at least 5mm or more. When the height of the antenna is less than 8mm, the radiation efficiency of the antenna may be limited. If the antenna performance is not good, the user embodiment is necessarily poor. In some cases where product ID stacking has been determined, the antenna environment is poor. For example, due to the limited structural space environment of the terminal product, various magnetic interferences exist in the product, and the radiation of the antenna is blocked by metals such as iron blocks, screens and the like, so that the radiation of the built-in antenna to a certain direction is strongest, the directivity is limited, and the efficiency of the built-in antenna is generally lower by about 30% and even lower. Therefore, in addition to improving the signal strength of the spatial environment, the user experience can be improved by providing the terminal product with a customized external antenna, increasing the antenna gain, and/or improving the radiation direction.

As shown in fig. 1, the present invention mainly provides a communication device 10 capable of switching an external antenna, where the communication device 10 capable of switching an external antenna includes at least an internal antenna module 11, an external antenna module 12, and a single-pole four-throw switch 13, where the single-pole four-throw module is electrically disposed between the internal antenna module 11 and the external antenna module 12, so as to control the single-pole four-throw switch 13 to communicatively connect the external antenna module 12 and the internal antenna module 11, thereby improving signal transmission capability of the communication device 10 capable of switching an external antenna.
In detail, in the first embodiment of the present invention, an internal antenna 111 is disposed in the internal antenna module 11, and the internal antenna 111 is in a default normally open state. At least one external antenna is disposed in the external antenna module 12. The external antenna module 12 is communicatively connected to the outside of the communication device 10 capable of switching the external antenna, the communication device 10 capable of switching the external antenna includes at least one power amplification module, and the single-pole four-throw switch 13 is disposed between the power amplification module and the internal antenna module 11.
Specifically, in the first embodiment of the communication device 10 with switchable external antenna according to the present invention, the internal antenna 111 is set in the form of PIFA due to the influence of the structure and space environment, and when in an open environment or a region with good signal, the internal antenna 111 is less interfered, so that the communication of signals can be realized.
Preferably, in the first embodiment of the present invention, the external antenna module 12 includes at least a first external antenna 121, a second external antenna 122, and a third external antenna 123, and the single-pole four-throw switch 13 includes four gears, three of the gears can be respectively connected to the first external switch, the second external switch, and the third external switch, and the remaining one is a neutral gear, so that the single-pole four-throw switch 13 can be respectively connected to the first external antenna 121, the second external antenna 122, and the third external antenna 123, so that the communication device 10 capable of switching external antennas can switch the single-pole four-throw switch 13 to connect different antennas in the external antenna module 12 according to different environments.
In the first embodiment of the present invention, the first external antenna 121 is implemented as an omnidirectional antenna, that is, its design function is focused on the radiation direction, and it shows 360 degrees of uniform radiation on the horizontal directional diagram, and there is a certain width of beam on the vertical directional diagram, so that it has a good structural space environment, and will not be interfered by the electromagnetic interference of the product theme, and has good antenna efficiency and directivity.
Preferably, the gain range of the first external antenna 121 is 9-12 dbi.
Therefore, the first external antenna 121 can still realize signal communication in a remote suburb, a mountain top, a high tower and other environments with weak signals. When the communication device 10 with switchable external antenna is in the above environment, the single-pole four-throw switch 13 may be connected to the first external antenna 121, so as to achieve smooth connection of signals.
In the first embodiment of the present invention, the design function of the second external antenna 122 focuses on directional polarization, that is, the second external antenna 122 is implemented as a directional polarized antenna, so that the second external antenna 122 has a large forward gain, and can suppress backward signals, thereby increasing the interference rejection capability.
Preferably, the gain of the second external antenna 122 is in the range of 15.5-18.5 dbi.
Therefore, in a more or more complex building environment and in an area where interference and multipath reflection are severe, the second external antenna 122 can still realize signal communication. In other words, when the communication device 10 with switchable external antenna is in the above environment, the single-pole four-throw switch 13 can be connected to the second external antenna 122, so as to achieve smooth communication of signals.
Further, in the first embodiment of the present invention, the third external antenna 123 is mainly designed to be dual polarized, that is, the third external antenna 123 is implemented as a dual polarized antenna, which combines polarization directions of +45 degrees and-45 degrees that are orthogonal to each other and simultaneously operates in the first-transmit duplex mode, so as to enhance the spatial diversity effect, and thus the third external antenna 123 has better antenna gain and stability.
When the communication device 10 with the switchable external antenna is located in an area with bad indoor signals, the single-pole four-throw switch 13 is connected to the third external antenna 123, so that the third external antenna 123 can exert the characteristic of communication in the communication area, and the communication effect of the communication device 10 with the switchable external antenna is not affected.

In other words, no matter whether the smart phone, the computer, the smart tablet or other smart wearable devices are provided, the communication device 10 including the switchable external antenna according to the present invention can achieve smooth and unobstructed information transmission in different environments.
In the first embodiment of the present invention, since the first external antenna 121, the second external antenna 122, and the third external antenna 123 are respectively disposed outside the communication device 10 capable of switching the external antennas, not only the communication structure of the communication device 10 capable of switching the external antennas can be reduced, but also the processing difficulty of the communication device 10 capable of switching the external antennas can be reduced, and in addition, the use cost of the communication device 10 capable of switching the external antennas can be reduced while ensuring the communication effect of the communication device 10 capable of switching the external antennas.

It should be noted that, in the first embodiment of the present invention, the first external antenna 121, the second external antenna 122 and the third external antenna 123 are respectively disposed outside in consideration of the structural problem, the manufacturing cost problem and the processing difficulty problem of the switchable external antenna communication device 10. In addition, those skilled in the art may also arrange one or more or all of the first external antenna 121, the second external antenna 122 and the third external antenna 123 inside the communication device 10 with switchable external antennas according to actual situations, and the present invention is also within the protection scope of the present invention. In other words, as long as the technical solution identical or similar to the present invention is adopted on the basis of the above disclosure of the present invention, the technical problem identical or similar to the present invention is solved, and the technical effect identical or similar to the present invention is achieved, all of which belong to the protection scope of the present invention, and the specific implementation manner of the present invention is not limited thereto.
The working principle of the external antenna switchable communication device 10 of the present invention is that, when the external antenna switchable communication device 10 is in an application process, the switch button 14 switches the first external antenna 121, the second external antenna 122, or the third external antenna 123 to be in communication connection with the internal antenna 111, so as to jointly implement signal transmission and transmit the signal to a radio frequency front end module 15 in the external antenna switchable communication device 10, the radio frequency front end module 15 exchanges information with a radio frequency transceiver chip 16 in the external antenna switchable communication device 10 through a transmitting or receiving channel, and then the radio frequency transceiver chip 16 implements information transmission with a CPU through an IO interface, thereby implementing transceiving transmission between external signals.
Next, the application of the communication device 10 with switchable external antenna according to the present invention in a practical environment will be illustrated.
Example 1
The communication device 10 with switchable external antenna is applied to an intelligent tablet computer. When a user carries the smart tablet computer outdoors, such as in an area like a park, normal transmission of signals can be achieved only through the internal antenna 111 in the internal antenna module 11 in the communication device 10 with the switchable external antenna. At this time, it is not necessary to control the single-pole four-throw switch 13 to be connected to the first external antenna 121, the second external antenna 122, or the third external antenna 123 through the switch button 14.
Example 2
The communication device 10 with switchable external antenna is applied to a smart phone. When a user carries the smart phone to a remote area to ascend a mountain and climbs to a certain height, for example, a mountain top of a mountain, a signal generated by the built-in antenna 111 in the smart phone becomes weak due to the influence of topography. In this case, the user only needs to control the single-pole four-throw switch 13 to connect the first external antenna 121 through the switch button 14, so that the first external antenna 121 and the internal antenna 111 jointly perform signal transmission. Due to the omnidirectional antenna performance of the first external antenna 121, the smart phone can recover normal signal transmission.
Example 3
The communication device 10 with switchable external antenna is applied to a smart watch. When a user wears the intelligent watch to work in a place with a complex structure and standing in a tall building, normal signal transmission is influenced due to the blockage of a plurality of buildings. At this time, the user only needs to control the single-pole four-throw switch 13 through the switch button 14 to connect the second external antenna 122, so that the second external antenna 122 and the internal antenna 111 jointly perform signal transmission. At this time, due to the performance of the directional polarization antenna of the second external antenna 122, the signal transmission capability of the smart watch in such an environment can be improved, so that the smart watch can perform normal signal transmission.
Example 4
The communication device 10 with switchable external antenna is applied to a desktop computer indoors. When the desktop computer is installed in an area with bad indoor signals, such as a laboratory that generates a shielding effect on signals through special processing, the internal antenna 111 in the desktop computer cannot perform normal signal transmission, and thus a user needs to control the single-pole four-throw switch 13 to connect the third external antenna 123 through the switch button 14, so that the third external antenna 123 and the internal antenna 111 perform signal transmission together. At this time, due to the performance of the dual-polarized antenna of the third external antenna 123, the antenna gain and stability are better, so that the desktop computer can perform normal signal transmission.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished.
