Description
Technical Field
The present application relates to the field of handheld communication devices, and in particular, to an antenna and a handheld communication device.
Background
Satellite communication is an effective means of communication in the event of insufficient coverage or poor signals from the cellular base station. There are several technical challenges to integrating satellite communication technology into handsets. Electromagnetic waves of current wireless communication of handheld communication devices with cellular base stations or other devices typically propagate in linear polarization. But the ground device is communicated with satellites which are far from hundreds of kilometers to thousands of kilometers, and the middle part of the ground device needs to pass through an atmosphere layer due to long propagation distance, and the linear polarization antenna can generate polarization distortion due to the Faraday rotation effect of an ionosphere; the circularly polarized wave is less affected by multipath effect and polarization distortion, has no strict placing posture requirement on the receiving antenna, and resists cloud and rain interference, so that the circularly polarized antenna is a better choice for satellite communication in order to improve the reliability and stability of satellite communication and effectively reduce the distortion and attenuation of communication signals.
The mobile phone has smaller volume, more internal metal parts and great difficulty in realizing the integration of the circularly polarized or axially lower elliptical polarized antenna. This makes it an urgent problem to be solved to realize a circularly polarized antenna for stable and reliable satellite communication without affecting portability of conventional handheld communication devices.
The signal strength decays during spatial transmission due to the spread of energy. This loss is proportional to the square of the distance, so the farther the signal is transmitted, the greater the free space loss. Satellite communications have very large free space losses because of the very large transmission distances. Therefore, the satellite antenna of the mobile terminal can provide an antenna with higher gain, so that the stability of the satellite-to-ground communication link can be better ensured.
In satellite communications, the wider the bandwidth, the faster the transmission rate. This is because the bandwidth determines the amount of data that can be transmitted by the signal, and if the bandwidth is narrow, the amount of data transmitted by the signal is limited, and the transmission rate is correspondingly slowed down. Conversely, if the bandwidth is wider, the larger the amount of data that the signal can transmit, the faster the transmission rate. The mobile terminal body needs to support a wider bandwidth for higher rate communications using satellites. Whether higher gain antennas or wider bandwidth antennas, it is desirable that the antennas have a higher profile height. How to meet the requirement of higher antenna profile height without affecting the thickness of the whole terminal equipment is a problem to be solved.

Detailed Description

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
As shown in fig. 1-6, the present application discloses an antenna for a handheld communication device, comprising:
an antenna main body 1, including a circularly polarized or elliptically polarized antenna unit 11, disposed on a mobile terminal main body 3, wherein the antenna unit 11 is electrically connected with the mobile terminal main body 3, and is used for connecting a radio frequency signal of the antenna unit 11 into the mobile terminal main body 3, and receiving and transmitting the signal when communicating with a target object; 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.
The antenna unit 11 comprises a radiating unit 12, an adjustable supporting mechanism 13 and a ground component 14, wherein the adjustable supporting mechanism 13 is respectively connected with the radiating unit 12 and the ground component 14 and is used for providing adjustable supporting force for the radiating unit 12 and the ground component 14 and adjusting the relative distance between the radiating unit 12 and the ground component 14 to reach the target section height so as to realize the variable adjustment of the thickness of the antenna unit 11 in a satellite communication mode and a non-satellite communication mode of the antenna unit 11. 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.
A position adjusting mechanism 3 connected to the antenna body 1 for adjusting the use posture of the antenna body 1 and ensuring that the antenna body 1 is kept at a preset position with respect to the mobile terminal body 3 such that the direction of radiation of the antenna body 1 is directed toward the propagation direction of the satellite antenna beam;
the antenna main body 1 is switched between an unfolding state and a folding state through the position adjusting mechanism 3, so that the antenna main body 1 is switched between a satellite communication mode and a non-satellite communication mode, corresponding deformation force is generated in the unfolding state and the folding state, and the thickness of the antenna unit 11 is optimized on the basis of not changing the thickness of the mobile terminal main body 3 so as to achieve the target section height of the antenna. The target profile height described in the present embodiment refers to a higher profile height of the antenna that can be achieved without changing the thickness of the mobile terminal body 3.
In the non-satellite communication mode, the position adjusting mechanism 2 is controlled to drive the antenna unit 11 to generate a first deformation force in the non-satellite communication mode and a second deformation force in the satellite communication mode when moving so as to adjust the section height of the antenna to realize the change adjustment of the thickness of the antenna unit 11; the position adjusting mechanism 2 controls the position relation of the antenna main body 1 relative to the mobile terminal main body 3 so as to realize the position switching of the antenna main body 1 in the satellite communication mode and the non-satellite communication mode and enter the corresponding mode. In the present embodiment, the antenna body 1 can realize a terrestrial communication function also in the non-satellite communication.
In one 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 spread the antenna body 1 to trigger a satellite communication mode. As will be understood by those skilled in the art, the antenna provided by the embodiment of the present application is composed of an antenna main body 1, a position adjusting mechanism 2 and a mobile terminal main body 3, and the antenna main body 1 is connected to the terminal apparatus main 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.
See fig. 7-11; in one embodiment, the position adjusting mechanism 2 is disposed on the antenna body 1, and the radiating unit 12, the adjustable supporting mechanism 13, and the ground component 14 are connected in order. For adjusting the relative distance between the radiating element 12 and the ground element 14 to a target profile height, the thickness of the antenna element 11 is optimized to the target profile height of the antenna without changing the thickness of the mobile terminal body 3.
In another embodiment, the position adjusting mechanism 2 is disposed at two sides of the antenna main body 1, that is, at two sides of the radiating unit 12 and the ground component 14, and the position adjusting mechanism 13 used at this time may be a sliding rail for adjusting the relative distance between the radiating unit 12 and the ground component 14 to reach the target profile height, so that the thickness of the antenna unit 11 is optimized to reach the target profile height of the antenna without changing the thickness of the mobile terminal main body 3.
In another embodiment, the adjustable supporting mechanism 13 includes a lifting mechanism body, where the lifting mechanism body includes an upper platform, a lower base, and a lifting body located between the upper platform and the lower base, where the upper platform, the lifting body, and the lower base are fixedly connected, and the radiating unit 12 is fixedly connected to the upper platform, and the ground component 14 is fixedly connected to the lower base, and is configured to drive, through the lifting body, the upper platform and the lower base to move in a vertical direction, so as to drive a relative distance between the radiating unit 12 and the ground component 14 to reach a target profile height.
In one embodiment, the radiation direction of the antenna body 1 is opposite to the propagation direction of the satellite antenna beam, 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 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.
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.
The signal strength decays during spatial transmission due to the spread of energy. This loss is proportional to the square of the distance, so the farther the signal is transmitted, the greater the free space loss. Satellite communications have very large free space losses because of the very large transmission distances. Therefore, the satellite antenna of the mobile terminal can provide an antenna with higher gain, so that the stability of the satellite-to-ground communication link can be better ensured.
In satellite communications, the wider the bandwidth, the faster the transmission rate. This is because the bandwidth determines the amount of data that can be transmitted by the signal, and if the bandwidth is narrow, the amount of data transmitted by the signal is limited, and the transmission rate is correspondingly slowed down. Conversely, if the bandwidth is wider, the larger the amount of data that the signal can transmit, the faster the transmission rate. The mobile terminal body 3 needs to support a wider bandwidth for higher rate communication using satellites.
Whether higher gain antennas or wider bandwidth antennas, it is desirable that the antennas have a higher profile height. In order to obtain a higher profile height, in this embodiment, the mobile terminal body 3 is provided with an installation portion 4 formed by recessing inwards, a structure to be installed formed by connecting the antenna body 1 and the position adjustment mechanism 2 is accommodated in the installation portion 4, and in a non-satellite communication mode, the antenna body 1 and the position adjustment mechanism 2 are accommodated in the installation portion 4, so that the radiating unit 12 and the ground component 14 are in a pressed state to reach a first target profile height; in the satellite communication mode, the antenna body 1 is unfolded by the position adjusting mechanism 2 so that the radiating unit 12 and the ground assembly 14 are in a sprung-open state to reach a second target profile height.
As will be appreciated by those skilled in the art, the antenna unit 11 employed in this embodiment is comprised of a radiating portion and a ground assembly 14. The distance between the radiating portion and the ground assembly 14 is the cross-sectional height of the antenna, which is adjustable in height under different operating conditions. In the non-satellite communication state, the antenna unit 11 and the flip assembly are housed in the recessed structure of the chassis, where the antenna unit 11 and the flip assembly housed in the chassis, i.e., the above-described structure to be mounted, the radiation portion of the antenna unit 11 and the ground assembly 14 are pressed together to assume a first target profile height, which is a low profile state. In the satellite communication state, the antenna unit 11 is flipped out by the flip assembly, and the radiating portion of the antenna unit 11 and the ground assembly 14 are flipped open to assume a second target profile height, which is a high profile state, to achieve a higher gain and a wider bandwidth.
As shown in fig. 9, the bottom surface of the ground component 14 is made of metal, which is favorable for realizing the function of antenna ground, increasing the signal strength and enhancing the anti-interference capability of the antenna.
Specifically, as shown in fig. 7 and 10, the upper surface of the ground component 14 is provided with a plurality of through holes 5, and the adjustable supporting mechanism 13 is installed in the through holes 5, and is used for adjusting the use state of the antenna main body 1 so as to control the relative distance between the ground component 14 and the radiating unit 12, so as to realize the adjustment of the profile height.
Specifically, the adjustable supporting mechanism 13 includes pogo pins, compression springs, sliding rails, a lever mechanism or other elastic connectors, and other distance adjusting members, and the elastic connectors in this embodiment are electrically connected to the metal ground and the radiating unit 12 on the one hand, and push the ground component 14 away from the radiating unit 12 on the other hand, so as to realize adjustment of the profile height.
In one embodiment, as shown in fig. 10, the ground assembly 14 extends outwardly along the upper surface to form a support portion 6, and the support portion 6 is integrally formed with the ground assembly 14.
