Description

METHOD AND SYSTEM FOR DIRECTING RADIO FREQUENCY RAYS TO RADIO FREQUENCY ANTENNA
FIELD OF INVENTION
The present application generally relates to the field of electromagnetic radiations and more particularly to a system and method for directing radio frequency rays to a RF antenna.
BACKGROUND
This section is intended to provide information relating to field of the invention and thus any approach or functionality described below should not be assumed to be qualified as prior art merely by its inclusion in this section.
The radio frequency (RF) rays are a type of electromagnetic energy and are associated with various electric and magnetic properties. The RF rays are widely used in communication as well as non-communication systems. For example, RF rays are used for signal transmission and broadcasting in communication system and also used in various non-communication systems such as microwave ovens, radars and various industrial processes.
It is a property of the RF rays that the said rays gets absorbed by the human body at a specific rate (SAR) , which leads to negative impact on the health of human beings. The specific absorption rate (SAR) is a measure of the rate at which the RF energy is absorbed by the human body, wherein the said measurement is in watts per kilogram. The SAR is calculated when the human body is exposed to a radio frequency (RF) electromagnetic field.
Further, the absorption of the RF rays depends upon a number of factors such as the absorption of RF energy is more in the resonant conditions, for instance, when the wavelength of the RF rays are comparable to the dimensions of a human body then more RF energy gets absorbed by said human body. Along with this, SAR value also depends on the frequency, polarization and intensity of RF Field, which as an end user can’t be controlled.
In an electronic device which is using a wireless network, there will be some RF loss, which will increase SAR level of said device. Also there are instances where the loss of RF rays/signals may occur which leads to the poor quality signals at the destination, as the RF rays not properly directed to the antenna of the electronic device/destination. Further, there may be situations, for instance, where the recommended limits for safe exposure of human beings to RF rays could exceed, such as in an environment near the high-powered RF sources. In such situations, proper control measures or actions are required to ensure the safe use of RF rays/signals.
A number of exposure standards for RF energy/signals have been developed over the past few years. These standards recommends safe levels of exposure to the RF signals to avoid the ill effects of RF rays. Further, for different electronic devices, different safe levels of exposure to the RF signals are specified. In an instance, the SAR values related to cellular phones are measured by considering the cellular phone’s position and calculating the amount of  radiations absorbed by the human head when close to the antenna of the cellular phone, or while talking over said cellular phone.
In order to reduce the negative impacts of RF rays and to provide better signal quality there arises a need for proper management of the RF rays. Also a number of solutions to provide better management of RF signals have been developed, but said prior art solutions fails to direct the RF signal path. The prior art solutions also failed to control the dissipate RF rays, further leading to loss of signals/rays and harmful effects on users.
Furthermore, the prior art solutions lacks both manual and automatic methods to direct the RF signals. In view of these and other existing limitations, there arises an imperative need to provide a solution to overcome the limitations of prior existing solutions and to provide a more efficient method and system for directing radio frequency rays to a RF antenna.

The two RF lenses [206 (A) ] and [206 (B) ] of the electronic device [200] are further connected to the reflector [204] , wherein said reflector [204] is configured to reflect RF rays [208] received from the RF lenses [206 (A) ] and [206 (B) ] . The reflector [204] directs/reflects the RF rays [208] towards the RF antenna [202] . In an instance the placement of the reflector [204] in said electronic device is such that the maximum RF rays [208] are directed towards the RF antenna [202] .
The electronic device [200] also comprises at least one motor connected to said reflector [204] , two RF lenses [206 (A) ] and [206 (B) ] and processor [212] . The said motor is configured to receive the at least one second parameter from the processor. The motor further automatically cause a change in configuration of at least one of the at least one RF lenses [206 (A) ] and [206 (B) ] and the reflector [204] , based on said at least one second parameter, to direct said RF rays [208] to the RF antenna [202] . In an event the said direction of RF rays towards the RF antenna may be achieved via unidirectional direction or multidirectional path as may be necessary to implement the features of the invention in said particular event.
Referring to Fig. 3, an exemplary method flow diagram [300] , depicting method for directing radio frequency rays to a RF antenna, in accordance with exemplary embodiment of the present disclosure is shown. As shown in Fig. 3, the method begins at step [302] .
At step [304] , the method comprises receiving RF rays at an at least one RF lens [102] and an at least one reflector [108] . The RF rays are received from at least one base station. The  said at least one RF lens [102] and an at least one reflector [108] are configured to direct maximum received RF rays towards the RF antenna of an electronic device. The direction of said RF rays towards the RF antenna provides the better signal strength and also reduces the SAR value. Further the RF reflector [108] is also configured to receive RF rays from the RF lens [102] . The reflector [108] , reflects said received RF rays towards the RF antenna.
Thereafter at step [306] , at least one first parameter is monitored by at least one sensor [104] , wherein said at least one first parameter may include but not limited to one of an ambient temperature, speed and location. The sensor [104] may be a temperature sensor, proximity sensor, location sensor, accelerometer, gyroscope, magnetometer, barometer, GPS, ambient light sensor and the other sensors obvious to the person skilled in the known art.
The method further at step [308] comprises, receiving, by a processor [106] , said at least one first parameter from the at least one sensor [104] and after receiving said first parameter, the processor [106] , at step [310] determines at least one second parameter based on at least the received at least one first parameter. The said second parameter is one of a desired gradient of said at least one RF lens [102] , circular symmetry of the lens [102] and polar coordinates of the lens [102] .
Furthermore, the method at step [312] encompasses, receiving, by a motor [110] , the at least one second parameter from the processor [106] . The motor [110] at step [314] , on receipt of said second parameters from the processor [106] , is further configured to automatically causing a change in a configuration of at least one of the at least one RF lens [102] and at least one reflector [108] , based on said at least one second parameter, to direct said RF rays to the RF antenna. In an event the said direction of RF rays towards the RF antenna may be achieved via unidirectional direction or multidirectional paths as may be necessary to implement the features of the invention in said particular event. Thereafter, the method terminates at step [316] , after directing radio frequency rays to a RF antenna.
Also, in an instance the user may provide manual inputs to direct said RF rays to the RF antenna, wherein the user input may include positioning of the at least one RF lens [104] and at least one reflector [108] to direct maximum RF rays towards the RF antenna and also to adjust the SAR value of an electronic device. Thereafter, the processor [106] , determine at least one second parameter based on at least one first parameter received from sensor [104] and the user input. Further, the at least one motor [110] , receives said at least one second parameter from the processor [106] and then causes a change in configuration of at least one of the at least one RF lens [102] and at least one reflector [108] , based on said at least one second parameter, to direct said RF rays to the RF antenna and to reduce the effect of SAR value of the RF rays.
Also, the method of directing radio frequency rays to a RF antenna may be explained by the following examples:
In an instance, when the weather is bad and the signal strength is low, the sensor [104] may monitor at least one first associated parameter related to the weather conditions. The processor [106] then determines at least one second parameter based on the said at least one first parameter. Thereafter the motor [110] on the basis of said second parameters changes the configuration of at least one of the at least one RF lens [102] and at least one reflector [108] and as a result the lens functionality will be minimized, and the gradient will be reset to receive maximum signals.
In one more instance, if an electronic device is not in motion, the sensor [104] may monitor at least one first associated parameter related to the movement of said electronic device/device. The processor [106] then determines at least one second parameter based on the said at least one first parameter. Thereafter the motor [110] on the basis of said second parameters changes the configuration of at least one of the at least one RF lens [102] and at least one reflector [108] and as a result the gradient can be varied to a value where the maximum RF rays can be re-directed, as there is no change of base station or direction for RF rays in still devices.
In yet another instance, other rules can also be defined, where based on current environment and RF rays intensity and direction, the lens functionality can be optimized to receive a balanced RF rays for good signal quality and minimum dissipate rays.
Referring to Fig. 4, an exemplary sequence flow diagram [400] , for directing radio frequency rays to a RF antenna, in accordance with exemplary embodiment of the present disclosure is shown. As shown in Fig. 4, the process begins at step [402] and proceeds further wherein the RF rays are received at a RF lens [102] from a base station at step [404] .
Thereafter the RF lens [102] is configured to collect the said RF rays at step [406] . The RF lens [102] may be a single RF lens or a combination of multiple RF lenses as may be necessary to implement the features of the invention.
Further at step [408] , the electronic device/device is configured to check whether the directing of radio frequency rays to a RF antenna is to be achieved via an automatic mode or input based mode. If said mode is an input based mode, the process further leads to step [410] or if said mode is automatic mode the said process will lead to step [416] .
Next, at step [410] , the electronic device receives a manual input to direct radio frequency rays to a RF antenna. Thereafter, the user at step [412] can manually set the parameters or the user can turn off the input based mode. In an instance the said manual setting of parameters may include the adjustment of the received RF rays by manually directing the RF rays towards RF antenna. The processor [106] on the basis of said manual inputs and at least one first parameter, determine at least one second parameter. The said at least one second parameter may include but not limited to one of a gradient of said at least one RF lens, circular symmetry of the electronic device and polar coordinates of the electronic device.
Next, if the user turns off the input based mode on step [412] , the step [412] then leads to step [414] . At step [414] said input mode is disabled and which further leads to termination of the process at step [422] .
Also, if the user manually sets the parameters at step [412] , the step [412] then leads to step [420] . At step [420] the RF lens [102] will start working based on the input mode to direct said RF rays to the RF antenna. Further, at least one motor [110] is configured to automatically cause a change in a configuration of at least one of the at least one RF lens and at least one reflector, based on said at least one second parameter and said manual input, to direct said RF rays to the RF antenna. After manually directing radio frequency rays to a RF antenna at step [420] , the process further terminates at step [422] .
Furthermore, if at step [408] , the electronic device is operating in automatic mode to direct radio frequency rays to a RF antenna, the process will further leads to step [416] . At step [416] , the at least one parameter (second parameter) can be set automatically on the basis of  sensor input i.e. first parameter (such as per location, weather, signal or speed) . The processor [106] is configured to determine at least one second parameter on the basis of at least one first parameter, wherein the said first parameter is monitored by the sensor [104] . The said at least one second parameter includes at least one of a gradient of said at least one RF lens, circular symmetry of the electronic device and polar coordinates of the electronic device.
Thereafter, the process at step [418] encompasses automatically setting of appropriate parameters to direct the said RF rays to the RF antenna. Further at step [420] the RF lens [102] will start working based on the automatic mode. If the signal strength changes in the automatic mode the parameters will be changed automatically. Also, at least one motor [110] is configured to automatically cause a change in a configuration of at least one of the at least one RF lens and at least one reflector, based on said at least one second parameter, to direct said RF rays to the RF antenna automatically.
After automatically directing radio frequency rays to a RF antenna at step [420] , the process further terminates at step [422] .
