The antenna module is composed of a feed unit array, and the feed unit array comprises a plurality of feed units. In some embodiments, all of the feed elements in the array of feed elements radiate electromagnetic waves together. In the embodiment of the present application, part of the power feeding units in the power feeding unit array perform electromagnetic wave radiation, and the number of the power feeding units performing electromagnetic wave radiation in the power feeding unit array can be adjusted as needed.

In addition, those skilled in the art will appreciate that the structure of the terminal 100 shown in the above figures is not intended to limit the terminal 100. In some embodiments, terminal 100 includes more or fewer components than shown, or some of the components are combined, or a different arrangement of components. For example, the terminal 100 further includes a display screen, which is a display component for displaying a user interface.

In addition, the terminal 100 further includes a microphone, a speaker, a radio frequency circuit, an input unit, a sensor, an audio circuit, a Wireless Fidelity (Wi-Fi) module, a power supply, a bluetooth module, and other components, which are not described herein again.

With the development of communication technology, the frequency band of electromagnetic waves used in the communication process is wider and wider. In the Fifth Generation mobile communication System (5G), two millimeter wave bands of main frequency bands are used, including: below 6GHz and above 6 GHz. The frequency bands below 6GHz include 450MHz to 6GHz, also called Sub6G (below 6 GHz). The frequency range of 6GHz or more is 24GHz to 52GHz, and most of electromagnetic waves in this frequency band are electromagnetic waves of millimeter order. Electromagnetic waves of millimeter level refer to electromagnetic waves of 1-10 millimeters, also known as millimeter waves. The millimeter wave is in the overlapping wavelength range of microwave and far infrared wave, so that it has the characteristics of two wave spectrums, and is the main frequency band of next-generation communication. Millimeter wave array antennas are generally used for communication through millimeter waves, and are planar or three-dimensional antenna arrays realized in a mode of equal amplitude and equal phase.

In the related art, an electromagnetic wave Absorption ratio (SAR) is used as an electromagnetic wave Absorption parameter for measuring the Absorption of electromagnetic waves. The SAR value and the transmission power of the terminal millimeter wave antenna for radiating the electromagnetic wave are in a direct proportion relationship, namely the higher the transmission power is, the higher the SAR value is. Therefore, the most direct method for reducing the SAR value is to reduce the transmission power of the millimeter wave antenna for radiating the electromagnetic wave, that is, to reduce the SAR value of the terminal by reducing the transmission power of the feed element array of the millimeter wave antenna. However, in some cases where the working scene of the terminal changes, when the SAR value needs to be reduced greatly, the transmission frequency of the feed unit array needs to be reduced greatly, which further causes the transmission power of the feed unit array to be lower and the communication quality of the terminal to be reduced.

For example, when the terminal is switched from a standby scene to a call scene, since the user is generally required to place the terminal at the ear during the call, the distance between the terminal and the user is almost 0, and thus the SAR value of the terminal needs to be reduced to a very low value to ensure that the electromagnetic wave radiation between the user and the terminal can meet the standard.

In the embodiments of the present application, in response to a need to reduce the value of the electromagnetic wave absorption parameter, the number of the feed units for performing electromagnetic wave radiation in the feed unit array is reduced. Due to the fact that the number of the feeding units used for conducting electromagnetic wave radiation is reduced, the gain of the feeding unit array is reduced, and the electromagnetic wave absorption parameter value generated when the feeding unit array conducts electromagnetic wave radiation is further reduced. Therefore, the electromagnetic wave absorption parameter value can be reduced without reducing the transmitting power of the feed unit, so that the electromagnetic wave absorption parameter meets the requirement and the communication quality is ensured.

Referring to fig. 2, a flowchart of an electromagnetic wave absorption parameter control method according to an exemplary embodiment of the present application is shown. The execution subject in the embodiment of the present application is the terminal 100, or the processor 110 in the terminal 100 or the operating system in the terminal 100, and the execution subject is taken as the terminal 100 in the embodiment for example. The method comprises the following steps:

step 201: and determining a first electromagnetic wave absorption parameter value generated by electromagnetic wave radiation through a first feeding unit group in the feeding unit array at present in response to the target scene being triggered.

Step 202: and determining a second feeding unit group from the feeding unit array in response to the first electromagnetic wave absorption parameter value being larger than a second electromagnetic wave absorption parameter value, wherein the second electromagnetic wave absorption parameter value is the highest electromagnetic wave absorption parameter value preset in the target scene, and the number of feeding units included in the second feeding unit group is smaller than that of feeding units included in the first feeding unit group.

Step 203: and performing electromagnetic wave radiation through the second feeding unit group, wherein the value of an electromagnetic wave absorption parameter generated by performing electromagnetic wave radiation through the second feeding unit group is not more than the value of the second electromagnetic wave absorption parameter.

In some embodiments, the determining a second group of feed elements from the array of feed elements according to the second electromagnetic wave absorption parameter value includes:

the second feeding element group is determined from the at least one feeding element group based on a current operating state of the feeding element array.

In some embodiments, the determining the second feeding element group from the at least one feeding element group based on the current operating state of the feeding element array includes:

acquiring a corresponding relation between a scene and a preset highest electromagnetic wave absorption parameter value in the scene;

and according to the target scene, determining a second electromagnetic wave absorption parameter value corresponding to the target scene from the corresponding relation between the scene and the highest electromagnetic wave absorption parameter value preset in the scene.

determining at least one scene;

In some embodiments, the electromagnetic wave radiation by the second feeding unit group includes:

according to the second feeding unit group, the working state of the feeding units in the second feeding unit group in the feeding unit array is changed into a radiation state, and the working states of the feeding units outside the second feeding unit group are changed into a standby state.

In some embodiments, the method further comprises:

Referring to fig. 3, a flowchart of an electromagnetic wave absorption parameter control method according to an exemplary embodiment of the present application is shown. The execution subject in the embodiment of the present application is the terminal 100, or the processor 110 in the terminal 100 or the operating system in the terminal 100, and the execution subject is taken as the terminal 100 in the embodiment for example. The method comprises the following steps:

step 301: in response to the target scene being triggered, the terminal determines a first electromagnetic wave absorption parameter value currently generated by electromagnetic wave radiation through a first feeding unit group in the feeding unit array.

The first electromagnetic wave absorption parameter value is any parameter value used for representing an electromagnetic wave absorption parameter. For example, the first electromagnetic wave absorption parameter value is an SAR value or the like. The first feeding unit group is a feeding unit group composed of all feeding units in the feeding unit array, or the first feeding unit group is a feeding unit group composed of part of feeding units in the feeding unit array. In the embodiments of the present application, this is not particularly limited. The target scene refers to a scene in which the electromagnetic wave absorption parameter value of the terminal needs to be adjusted. For example, the target scene is a scene in which a call is made through the terminal, a scene in which a distance between the terminal and the user is less than a preset distance, and the like. Correspondingly, the following ways of determining that the target scene is triggered by the terminal are available:

in some embodiments, a distance detector is installed in the terminal, the terminal detects a distance between the user and the terminal through the distance detector, and in response to the distance being less than a preset threshold, it is determined that the target scene is triggered. It should be noted that, in this implementation manner, the terminal can determine to trigger different target scenes through different preset thresholds. For example, a developer sets a first preset threshold and a second preset threshold in advance, and in response to the fact that the distance detected by the terminal is smaller than the first preset threshold, the terminal determines that the first scene is triggered, and determines the first scene as the target scene. And in response to the fact that the distance detected by the terminal is smaller than a second preset threshold value, the terminal determines that the second scene is triggered, and determines the second scene as a target scene.

In other embodiments, the terminal monitors the operating state of the terminal, and determines that the target scene is triggered in response to monitoring that the terminal opens a call. The call state includes a call state in which a call is performed through a call function of the terminal itself, or a call state in which a call is performed through an application such as social software. In the embodiment of the present application, the communication mode of the terminal is not specifically limited. Optionally, the call is opened to enter an application program with a call function for the terminal, or the terminal answers a call to the user through a sensor.

In other embodiments, the terminal includes an image collector, the image collector collects an image in a target direction of the terminal, distance detection is performed on a target object in the image in the target direction, and in response to detecting that a distance from the terminal to the target object in the collected image is smaller than a preset distance corresponding to the target object, it is determined that the target scene is triggered. The target object is the head or any other part of the user. In some embodiments, different target objects correspond to different preset distances, and thus to different target scenes.

It should be noted that the terminal can simultaneously detect whether any of the above-mentioned scenes is triggered, and determine the detected triggered scene as a target scene.

After the terminal detects that the target scene is triggered, the terminal determines a first electromagnetic wave absorption parameter value generated by electromagnetic wave radiation of the first feeding unit group. The first electromagnetic wave absorption parameter value is an electromagnetic wave absorption parameter value generated when the terminal carries out electromagnetic wave radiation in a working scene before a target scene. In some embodiments, the terminal records the first electromagnetic wave absorption parameter value in the current scene every time the scene is switched, and accordingly, in this step, the terminal directly calls the recorded first electromagnetic wave absorption parameter value. In other embodiments, the terminal determines the first electromagnetic wave absorption parameter value according to the current working state of the feed cell array, and referring to fig. 4, the process is implemented by the following steps (1) - (3), and includes:

(1) the terminal determines a second number of feed elements in the array of feed elements that radiate electromagnetic waves based on the first group of feed elements.

And the terminal records the current working state of the feed unit array according to the first feed unit group. In some embodiments, the terminal stores a cell identification for each feed cell in the first set of feed cells. Accordingly, the terminal records the feeding unit radiating the electromagnetic wave in the feeding unit array through the recorded unit identification of the feeding unit. Wherein, the element identification is the identification of the number of the feeding element, the coordinate in the feeding element array, and the like.

In this step, the terminal determines the feeding units in the feeding unit array in the state of radiating electromagnetic waves based on the working state of the feeding unit array, and counts the second number of the feeding units radiating electromagnetic waves.

In some embodiments, the terminal registers a first group of feed elements of the array of feed elements, and stores in advance a second number of feed elements corresponding to different groups of feed elements. For example, referring to fig. 5, the feeding element array is a 4 × 6 feeding element array including a plurality of feeding element groups, e.g., a first kind of feeding element group is 2 × 3 feeding element groups, i.e., a second number is 6; the second number of feed element groups is 1 x 4, i.e. the second number is 4. In other embodiments, the terminal directly detects a first group of feeding elements in the array of feeding elements that radiate electromagnetic waves, and counts a second number of feeding elements in the first group of feeding elements.

(2) And the terminal acquires a third electromagnetic wave absorption parameter value generated when each feed unit carries out electromagnetic wave radiation.

In some embodiments, the terminal stores a third electromagnetic wave absorption parameter value for each feed unit, and determines the first electromagnetic wave absorption parameter value based on the second number and the third electromagnetic wave absorption parameter value for each feed unit. Correspondingly, before the step, the terminal acquires a third electromagnetic wave absorption parameter value of each feed unit, and stores the third electromagnetic wave absorption parameter value locally. And the terminal receives the third electromagnetic wave absorption parameter value of each power feeding unit input by the developer. The third electromagnetic wave absorption parameter value is estimated by the developer, or is detected by the developer by using the electromagnetic wave absorption parameter, which is not specifically limited in the embodiment of the present application.

It should be noted that the third electromagnetic wave absorption parameter value of each feeding unit is the same or different, and this is not particularly limited in the embodiment of the present application.

(3) The terminal determines the product of the third electromagnetic wave absorption parameter value and the second quantity as the first electromagnetic wave absorption parameter value.

In this step, the terminal determines a first electromagnetic wave absorption parameter value of the current working state of the feed unit array based on the second number of the feed units and the third electromagnetic wave absorption parameter value of each feed unit. In this implementation, the third electromagnetic wave absorption parameter value of each feed unit is the same.

It should be noted that the third electromagnetic wave absorption parameter values of each feed unit may be different, and at this time, the terminal sums the third electromagnetic wave absorption parameter values of each feed unit until the summation of the third electromagnetic wave absorption parameters of the second number of feed units is completed, so as to obtain the first electromagnetic wave absorption parameter value.

In other embodiments, the feeding efficiency of each feeding unit of the terminal and the transmission power of the currently radiated electromagnetic wave determine a third electromagnetic wave absorption parameter value of each feeding unit, and then sum the third electromagnetic wave absorption parameter values of a second number of feeding units to obtain a first electromagnetic wave absorption parameter value.

It should be noted that, in some embodiments, the terminal further directly records the first electromagnetic wave absorption parameter value of the power feeding unit array in different operating states, and accordingly, the above steps (1) - (4) are replaced by: and the terminal directly determines a first electromagnetic wave absorption parameter value corresponding to the working state from the corresponding relation between the working state and the first electromagnetic wave absorption parameter value according to the working state of the feed unit array. The first electromagnetic wave absorption parameter value corresponding to each working state is an electromagnetic wave absorption parameter value obtained by detection of developers.

Step 302: in response to the first electromagnetic wave absorption parameter value being greater than the second electromagnetic wave absorption parameter value, a second set of feed elements is determined from the array of feed elements.

The number of the feeding units included in the second feeding unit group is smaller than that of the feeding units included in the first feeding unit group, and the second electromagnetic wave absorption parameter value is a highest electromagnetic wave absorption parameter value preset in a target scene.

In some embodiments, according to the target scene, the terminal determines, from the correspondence between the scene and the feeding unit groups, a second feeding unit group corresponding to the target scene. Correspondingly, the terminal sets different feeding unit groups for different scenes, in the step, the terminal acquires the corresponding relation between the scenes and the feeding unit groups, and according to the target scene, the second feeding unit group corresponding to the target scene is determined from the acquired corresponding relation.

In other embodiments, the terminal determines a second set of feed elements from the array of feed elements based on the second electromagnetic wave absorption parameter value. Referring to fig. 6, in response to that any target scene is triggered, comparing a first electromagnetic wave absorption parameter value and a second electromagnetic wave absorption parameter value of the target scene, and in response to that the first electromagnetic wave absorption parameter value is greater than the second electromagnetic wave absorption parameter value, it indicates that a current electromagnetic wave absorption parameter value of the terminal exceeds a preset electromagnetic wave absorption parameter value corresponding to the target scene, and the number of feed units performing electromagnetic wave radiation in the feed unit array needs to be adjusted, so as to reduce the current electromagnetic wave absorption parameter value of the terminal.

In this step, the electromagnetic wave absorption parameter value of the terminal is reduced by modifying the feed unit in the feed unit array. Correspondingly, the terminal determines a second feeding unit group corresponding to the second electromagnetic wave absorption parameter value.

In some embodiments, the terminal stores in advance groups of feeding units corresponding to different values of the electromagnetic wave absorption parameter. Accordingly, in this step, the terminal determines, according to the electromagnetic wave absorption parameter value, a second feeding unit group corresponding to a second electromagnetic wave absorption parameter value from the correspondence between the electromagnetic wave absorption parameter value and the feeding unit group. For example, referring to fig. 5 continuously, in two target scenarios in this embodiment, in the 4 × 6 feeder cell array, when neither of the two target scenarios is triggered, all the feeder cells in the 4 × 6 feeder cell array are in a state of radiating electromagnetic waves, and in response to the first target scenario being triggered, in the 4 × 6 feeder cell array, the 2 × 3 feeder cell group is in a state of radiating electromagnetic waves, and the other feeder cells are in a standby state, where the feeder cells do not radiate electromagnetic waves. In response to the second target scene being triggered, the 1 × 4 feeding unit group is in a state of radiating electromagnetic waves, and the other feeding units are in a standby state.

In other embodiments, the terminal determines, according to the second electromagnetic wave absorption parameter value, a first number of the feed units corresponding to the second electromagnetic wave absorption parameter value, and determines, according to the first number, the second feed unit group from the feed unit array. Accordingly, referring to fig. 7, the process of determining the second feeding element group from the feeding element array by the terminal according to the second electromagnetic wave absorption parameter value is realized by the following steps (a1) - (A3), including:

(A1) and the terminal determines the first number of the feed units corresponding to the second electromagnetic wave absorption parameter value based on the second electromagnetic wave absorption parameter value.

In this step, the terminal determines a first number of the feed units corresponding to the second electromagnetic wave absorption parameter value according to the electromagnetic wave absorption parameter value of each feed unit and a second electromagnetic wave absorption parameter value allowed by the terminal.

(A2) The terminal determines at least one feed element group consisting of the first number of feed elements from the array of feed elements.

And the terminal determines the composition form of the feeding unit groups corresponding to the first number according to the first number, and determines at least one feeding unit group consisting of the feeding units of the first number in the composition form from the feeding unit matrix. For example, if the first number is 4, the termination determines that the 4 feeding elements are formed in the form of 1 × 4 or 2 × 2, and the termination determines from the array of feeding elements 1 × 4 feeding element groups and 2 × 2 feeding element groups, and determines these feeding element groups as feeding element groups formed by the first number of feeding elements.

(A3) The terminal determines the second feeding unit group from the at least one feeding unit group based on the current operating state of the feeding unit array.

The second feeding unit group is a feeding unit group composed of a plurality of adjacent feeding units, or the second feeding unit group is a feeding unit group composed of a plurality of feeding units separated by one feeding unit in the feeding unit array. It should be noted that the distance between adjacent feeding units in the feeding unit group is smaller than the wavelength of the radiated electromagnetic wave.

In this step, the terminal determines the feeding unit currently in a radiating electromagnetic wave state based on the first feeding unit group, and determines, as the second feeding unit group, the feeding unit group that changes the radiating state of the feeding unit the least, from the feeding unit currently in the radiating state and the at least one feeding unit group. The process is realized by the following steps (A3-1) - (A3-2), including:

the (a3-1) terminal determines at least one feed element currently in a radiation state based on the first feed element group.

In this step, the terminal reads the plurality of feeding units corresponding to the first feeding unit group based on the first feeding unit group. The terminal obtains a unit identifier of the current feed unit in the radiation state, or the terminal obtains a position coordinate of the current feed unit in the radiation state in the feed unit array.

The (a3-2) terminal determines, from the at least one feeding element group, a first feeding element group having the highest coincidence rate with the at least one feeding element in the radiation state.

In this step, the terminal determines, from the at least one feeding unit group, a second feeding unit group having the highest coincidence rate with the at least one feeding unit currently in the radiation state, based on the at least one feeding unit in the radiation state.

It should be noted that, in some embodiments, after the at least one feeding element group is obtained, the step (a3) is not performed, and instead, the second feeding element group is randomly determined from the at least one feeding element group.

Another point to be noted is that, with continued reference to fig. 6, in response to the first electromagnetic wave absorption parameter value not being greater than the second electromagnetic wave absorption parameter value, the terminal need not reduce the number of the feed units in the feed unit array. In some embodiments, in response to the first electromagnetic wave absorption parameter value not being greater than the second electromagnetic wave absorption parameter value, the current operating state of the feed cell array is maintained. In other embodiments, in response to the first electromagnetic wave absorption parameter value not being greater than the second electromagnetic wave absorption parameter value, the terminal still performs the method of adjusting the number of the feeding units according to the second electromagnetic wave absorption parameter value, so as to increase the number of the electromagnetic waves subjected to electromagnetic wave radiation, thereby ensuring the communication quality of the terminal.

In some embodiments, only one target scene is stored in the terminal, and the terminal only needs to compare the first electromagnetic wave absorption parameter value with the second electromagnetic wave absorption parameter value corresponding to the target scene each time.

In other embodiments, a plurality of object scenes are stored in the terminal, and different object scenes correspond to different values of the second electromagnetic wave absorption parameter. Correspondingly, before the step, a second electromagnetic wave absorption parameter value corresponding to the target scene is determined from the stored corresponding relation between the scene and the electromagnetic wave absorption parameter value. The process is realized by the following steps (B1) - (B2), including:

(B1) the terminal obtains the corresponding relation between the scene and the highest electromagnetic wave absorption parameter value preset in the scene.

The corresponding relation between the scene and the preset highest electromagnetic wave absorption parameter value in the scene stores a plurality of scenes and the preset highest electromagnetic wave absorption parameter value corresponding to each scene. In some embodiments, the terminal stores the corresponding relationship between the scene and the highest electromagnetic wave absorption parameter value preset in the scene locally. Correspondingly, the terminal calls the corresponding relation between the locally stored scene and the preset highest electromagnetic wave absorption parameter value in the scene through the data interface. In other embodiments, the corresponding relationship between the scene and the highest value of the electromagnetic wave absorption parameter preset in the scene is stored in the server. Correspondingly, the terminal sends an acquisition request to the server, the server receives the acquisition request, acquires the corresponding relationship between the scene and the highest electromagnetic wave absorption parameter value preset in the scene according to the acquisition request, and sends the corresponding relationship between the scene and the highest electromagnetic wave absorption parameter value preset in the scene to the terminal, and the terminal receives the corresponding relationship between the scene sent by the server and the highest electromagnetic wave absorption parameter value preset in the scene.

Before that, the terminal needs to determine the preset highest electromagnetic wave absorption parameter value corresponding to each scene. The process is realized by the following steps (B1-1) - (B1-3), including:

(B1-1) the terminal determines at least one scene.

The at least one scene is set and changed as needed, and in the embodiment of the present application, the at least one scene is not specifically limited. In some embodiments, the terminal determines at least one scene based on the distance of the terminal from the user. For example, the distance between the terminal and the user is less than a first preset distance, and the scene is determined as a first scene; and determining the scene as a second scene when the distance between the terminal and the user is less than a second preset distance. In other embodiments, the terminal determines the at least one scenario based on usage of the terminal. For example, the terminal may be started, a call may be made, an audio may be played, or a video may be played.

(B1-2) for each scene, the terminal acquires the highest electromagnetic wave absorption parameter value in that scene.

And the highest electromagnetic wave absorption parameter value corresponding to the scene is the highest electromagnetic wave absorption parameter value conforming to the electromagnetic wave absorption parameter value certification test under the scene. And under different scenes, the using scenes of the terminal are different, the distance between the terminal and the user is also different, and the corresponding highest electromagnetic wave absorption parameter values under different scenes are determined according to the distance between the terminal and the user. For example, in a call scene, the distance between the terminal and the user is almost 0, and thus, in this scene, the highest electromagnetic wave absorption parameter value is a small value, whereas in a video-watching scene, there is a distance between the terminal and the user, and thus, the highest electromagnetic wave absorption parameter value is slightly larger data.

In some embodiments, the developer tests the electromagnetic wave absorption parameter generated by the terminal in each scene to obtain the highest electromagnetic wave absorption parameter value corresponding to each scene, and stores the highest electromagnetic wave absorption parameter value corresponding to each scene into the terminal. In other embodiments, a developer tests electromagnetic wave absorption parameter values generated by a terminal in each scene to obtain the highest electromagnetic wave absorption parameter value corresponding to each scene, selects the smallest electromagnetic wave absorption parameter value from the highest electromagnetic wave absorption parameter values corresponding to each scene, and takes the electromagnetic wave absorption parameter value as the highest electromagnetic wave absorption parameter value corresponding to each scene.

(B1-3) the terminal stores the correspondence between the scene and the highest electromagnetic wave absorption parameter value.

The terminal stores the corresponding relationship between the scene and the highest electromagnetic wave absorption parameter value locally or the terminal transmits the corresponding relationship between the scene and the highest electromagnetic wave absorption parameter value to the server, and the server stores the corresponding relationship between the scene and the highest electromagnetic wave absorption parameter value. In the embodiments of the present application, this is not particularly limited.

(B2) And the terminal determines a second electromagnetic wave absorption parameter value corresponding to the target scene from the corresponding relation between the scene and the highest electromagnetic wave absorption parameter value preset in the scene according to the target scene.

In this step, the terminal queries the corresponding relationship between the scene and the highest electromagnetic wave absorption parameter value according to the target scene to obtain a second electromagnetic wave absorption parameter value corresponding to the target scene.

It should be noted that, in some embodiments, the terminal does not obtain the correspondence between the scene and the highest electromagnetic wave absorption parameter value, sends the target scene to the server storing the correspondence between the scene and the highest electromagnetic wave absorption parameter value, the server queries the correspondence between the scene and the highest electromagnetic wave absorption parameter value through the target scene, sends the second electromagnetic wave absorption parameter value corresponding to the queried target scene to the terminal, and the terminal receives the second electromagnetic wave absorption parameter value corresponding to the target scene sent by the server.

Step 303: the terminal radiates an electromagnetic wave through the second feeding unit group.

Wherein the value of the electromagnetic wave absorption parameter generated by the electromagnetic wave radiation through the second feeding unit group is not greater than the second value of the electromagnetic wave absorption parameter. In this step, the terminal changes the operating state of the feeding units in the feeding unit group in the feeding unit array to the radiation state and changes the operating state of the feeding units other than the feeding unit group to the standby state according to the feeding unit group.

In addition, the number of the feed units in a radiation state in the feed unit array is reduced, so that the beam binding capacity is weakened, the beam of the radiated electromagnetic wave is widened, and the lateral communication performance of the beam main lobe is improved.
