Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
Referring to fig. 1, the application discloses an antenna for a handheld communication device, comprising:
an antenna main body 1, including a circularly polarized or elliptically polarized antenna unit, disposed on the mobile terminal main body 3, where the antenna main body 1 is electrically connected to the mobile terminal main body 3, and is used for establishing a communication link between the antenna main body 1 and the mobile terminal main body 3, and for receiving and transmitting signals when communicating with a target object; the position and the posture of the antenna main body 1 can be adjusted to be in a storage state when the antenna main body 1 communicates with ground equipment, and the position and the posture of the antenna main body 1 can be also adjusted to enable the maximum gain direction of antenna radiation to be close to the propagation direction of satellite antenna beams, so that the pointing error loss of the antenna main body 1 is reduced, and the communication quality is improved. The target object used in this embodiment is a satellite, and in the case of realizing non-satellite communication, the target object may be the ground.
A position adjustment mechanism 2 connected to the antenna body 1 for adjusting the use posture of the antenna body 1 and controlling to ensure that the position of the antenna body 1 and the mobile terminal body 3 is kept at a preset position in a use state and the use posture of the antenna body 1 is adjusted so that the direction of radiation of the antenna body 1 is directed toward the propagation direction of the satellite antenna beam; the switching of the antenna body 1 between the unfolded state and the folded state is realized by the position adjusting mechanism 2, so that the antenna body 1 is switched between the satellite communication mode and the non-satellite communication mode. The position adjustment mechanism 2 employed in the present embodiment may be a tilting mechanism or other rotation mechanism. The antenna body 1 employed in the present embodiment can realize a satellite communication mode in an expanded state, and the antenna body 1 can realize a ground communication mode in any state, i.e., in an expanded state or in a collapsed/housed state.
The antenna body 1 is electrically connected with the mobile terminal body 3, and is configured to establish communication between the antenna body 1 and the mobile terminal body 3 to trigger a satellite communication mode, and control a positional relationship of the antenna body 1 relative to the mobile terminal body 3 through the position adjustment mechanism 2, so as to realize position switching of the antenna body 1 in the satellite communication mode and in the non-satellite communication mode, and enter a corresponding mode. At this time, the antenna main body 1 is connected with the radio frequency part in the mobile terminal main body 3 to trigger the satellite communication mode. It will be appreciated that the antenna body 1 may be configured to trigger a satellite communication mode as desired in the deployed state, or may be configured to be in a non-satellite communication mode in the deployed state. The radio frequency part described in this embodiment is the same as the radio frequency transmission module 7 described below.
In one embodiment, the radiation direction of the antenna body 1 is opposite to the propagation direction of the satellite antenna beam to achieve the maximum gain, and the propagation direction of the satellite antenna beam includes a satellite direct propagation beam, a ground station beam or an effective beam reflected or transmitted by the intelligent super-surface. Wherein, intelligent super surface (RIS) is an artificial electromagnetic surface structure with programmable electromagnetic property, which is developed by metamaterial technology. RIS is usually composed of a large number of carefully designed electromagnetic units, and by applying control signals to adjustable elements on the electromagnetic units, the electromagnetic properties of the electromagnetic units can be dynamically controlled, so that active intelligent regulation and control of space electromagnetic waves in a programmable manner are realized, and electromagnetic fields with controllable parameters such as amplitude, phase, polarization and frequency are formed. The RIS is deployed on the surface of various objects in a wireless transmission environment, so that the physical properties of a wireless channel can be changed. When the channel state is poor, the RIS can improve the transmission of information between the transmitter and the receiver by reflecting electromagnetic waves around obstacles, etc. RIS can improve the overall capacity and performance of the system by improving the channel environment. In order to solve the problem of larger path loss between the satellite and the ground when communicating with the satellite, an active RIS is introduced to enhance ground signals, so that effective communication between the mobile terminal and the satellite is better ensured. The maximum gain direction of the antenna body radiation is close to the propagation direction of the satellite antenna beam, and the propagation direction of the satellite antenna beam can be a satellite direct propagation beam, a ground station beam or an effective beam reflected or transmitted by the intelligent super surface.
In an embodiment, the antenna body 1 is electrically connected to the mobile terminal body 3 through the position adjustment mechanism 2, and the position adjustment mechanism 2 is adjusted to expand the antenna body 1 to trigger a satellite communication mode, in the satellite communication mode, the direction of radiation of the antenna body 1 is controlled to face the propagation direction of the satellite antenna beam in various use postures of the mobile terminal body 3, so that the antenna body 1 is aligned with the satellite load end beam, and minimum antenna pointing error loss is realized. At this time, the antenna main body 1 and the position adjustment mechanism 2 having the radio frequency part built therein are connected to the mobile terminal main body 3 to trigger the satellite communication mode. The radio frequency part described in this embodiment is the same as the radio frequency transmission module 7 described below.
As can be appreciated by those skilled in the art, the handheld communication device antenna provided in the embodiment of the present application is composed of an antenna body 1, a position adjusting mechanism 2 and a mobile terminal body 3, where the antenna body 1 is connected to the terminal device body through the position adjusting mechanism 2. Wherein the antenna main body 1 is independent of the main body of the mobile terminal main body 3, the influence of the complex structure inside the terminal on the antenna can be reduced. The mobile terminal body 3 adopted in the embodiment of the application can be a mobile phone or a tablet personal computer and the like.
Considering the transmission loss of the satellite-to-ground communication link, the frequency band adopted in the mobile terminal is mainly concentrated in the low frequency band such as L or S at present, and the lower the frequency is, the smaller the free space propagation loss is, so that the requirements on the antenna gain and the power consumption of the mobile communication terminal are relatively low, and the satellite mobile phone can be directly connected. As more constellation layouts evolve towards low-rail and even ultra-low-rail, the propagation loss of free space is greatly reduced due to the reduction of transmission distance, and in the future higher Ku/Ka and even Q/V frequency bands may also directly enter the mobile communication terminal.
In satellite communications, optimal reception may be achieved when the antenna transmission and reception match homopolarity. However, the satellite-ground communication distance is long, the environment where the transmission path passes is complex, and particularly, the anisotropic property of atmospheric molecules and rain and fog water drops in the troposphere can cause the polarization property of electromagnetic waves to be changed, which is commonly called depolarization effect. If a linear polarization antenna in a traditional handheld communication device is adopted, polarization mismatch loss can be caused after polarization distortion, and serious incapacity of communication can be caused directly. The circularly polarized antenna is less affected by multipath effect and polarization distortion, so that the distortion and attenuation of communication signals can be effectively reduced, the reliability and stability of satellite communication are greatly improved, and the circularly polarized antenna is a better choice for satellite communication.
In one embodiment, the circularly or elliptically polarized antenna elements are radiators with symmetry or rotational symmetry to achieve equal amplitude horizontal and vertical components. The antenna unit used in this embodiment is flat, such as an antenna unit formed of a PCB board, to achieve radiation of horizontal and vertical components having equal amplitudes and phase differences of 90 ° or 270 °. The antenna elements employed in this embodiment may be rectangular, square or other regular patterns, as shown in fig. 1-3.
At present, more low frequency bands are used, and the problem is that the antenna is large in size. The mobile communication device is generally approximately rectangular and thin in thickness. It is difficult to realize resonance with equal amplitude in both the thickness direction and the length (width) direction. In addition, the internal structure of the mobile phone is complex, and the implementation of the completely built-in broadband circularly polarized antenna is difficult. Therefore, the antennas of the handheld satellite devices in the market are usually large and striking, which can cause the terminal devices to be very thick and heavy, and do not accord with the characteristics and development trend of the thin and light intelligent mobile terminals used to by people.
In order to solve the above-mentioned drawbacks, the mobile terminal body 3 is provided with a mounting portion 4 for accommodating the antenna body 1 and the position adjusting mechanism 2, and is configured to completely accommodate the accommodating structure formed by folding the antenna body 1 and the position adjusting mechanism 2 in a non-satellite communication state, without increasing the thickness of the mobile terminal body 3. As will be appreciated by those skilled in the art, the housing portion of the mobile terminal body 3 employed in the present embodiment has a concave or convex structure adapted to the antenna unit and the position adjustment mechanism 2, and can fully house the antenna unit and the position adjustment mechanism 2 in a non-satellite communication state.

The mounting portion 4 used in this embodiment is a concave structure directly disposed on the outer surface of the mobile terminal body 3, that is, on the back of the mobile phone, and the mounting portion 4 in fig. 2 is a concave structure, that is, a structure formed by recessing the outer surface of the mobile terminal, which is beneficial to reducing the thickness and weight of the mobile phone. The housing of the handheld communication device is specially provided with a concave structure, as shown in fig. 4. In the non-satellite communication state, the antenna assembly is folded and stored in the concave structure of the mounting portion 4, and as shown in fig. 5, the antenna main body 1 and the position adjusting mechanism 2 are turned out from the concave structure of the mounting portion 4 before satellite communication, and the antenna assembly is turned to a position suitable for communication outside the mobile phone and stopped.

The antenna body 1 is connected with the other end of the first turnover mechanism 21 through the second rotation part 62, so that the antenna body 1 rotates steplessly relative to the first turnover mechanism 21 by taking the central line of the rotating shaft of the second rotation part 62 as the shaft, and the circumferential rotation of the antenna body 1 after turnover is realized. The center line of the rotation axis of the second rotating member 62 is a rotation axis disposed along the length direction of the first tilting mechanism 21, that is, a reference line in the reference Y-axis direction.
