“…The formation of the fixed zeros of the electric field at a finite distance from the system of radiators carried out by selecting the amplitude and phase difference of their currents [25]. The effectiveness of interference suppression lies in its main property: if two signals of the same amplitude interfere, then when adding in phase at a given point, the power rises to 3dB, and in antiphase it is suppressed to minus infinity dB [26], [27].…”

In this work, a numerical calculation was carried out in one of the universal programs for automatic electro-dynamic design. The calculation is aimed at obtaining numerical values for specific absorbed power (SAR). It is the SAR value that can be used to determine the effect of the antenna of a wireless device on biological objects; the dipole parameters will be selected for GSM1800. Investigation of the influence of distance to a cell phone on radiation shows that absorbed in the head of a person the effect of electromagnetic radiation on the brain decreases by three times this is a very important result the SAR value has decreased by almost three times it is acceptable results.

“…The direction of the beam scanning is directed by changing the operation frequency. The equation of the direct beam steering of the leaky-wave antenna is assumed by [9], [10]. Where θ(f) is the broadside angle, ko is the wavenumber, and β is defined as the phase constant.…”

<p class="Default">The radiation power in the endfire is decreased while the main beam of half substrate integrated waveguide scan from broadside to endfire in a forward. The design of half-width microstrip leaky-wave antenna (HW-MLWA) has been presented in this work to increase the power radiation near endfire by using the slots technique in the radiation element. This slot leads to a decrease the cross-polarization. The proposed design comprises one element of HW-MLWA with repeated meandered square slots in the radiation element. One aspect of this antenna is generated by using a half substrate integrated waveguide with a full tapered feed line. The proposed antenna was terminated by load of 50 Ω, and feed on the other end of the antenna. Finally, the suggested design is simulated and acceptable results were found. The released gain is increased from 10.6 dBi to 12 dBi at 4.3 GHz. This design is suitable for unmanned aerial vehicle UAVs at C band application.</p>

“…Our use of devices such as televisions, computers, laptops, e-readers and cell phones has increased exponentially over the past few decades (Tang et al, 2016a). The calculated model for charging an electronic device from the ambient EM waves is unusual in the literature (Tang et al, 2016b;Zeain et al, 2020;Guo et al, 2016;Kar et al, 2021;Dai et al, 2016;Kindl et al, 2020;Jiang et al, 2012;Beh et al, 2014;Zeng et al, 2017), despite its importance for coverage forecasts. Using the previous approaches, induced voltage was so low.…”

“…Implementing this model, charging problems can be reduced. Zeain et al (2020), the authors suggested a striphelical antenna with a parasitic circular patch for circular polarization. Two nearby Circularly Polarized (CP) resonances were created and a broad Axial Ratio (AR) bandwidth was obtained by combining the strip-helix and the parasitic patch.…”

Electronic device use is on the rise as more and more tasks in everyday life are conducted online. As a consequence, charging is a unique aspect of any electronic device. However, the capacity of any electronic device's battery is fixed. On the other hand, charging the unit at any time and in any place is incredibly difficult. As a result, people are having a difficult time charging their electronic devices. The goal of this project is to develop a theoretical antenna model and a circuit diagram to solve this problem. To absorb EM waves from the environment and to inclusively to charge the battery, an extra helical antenna is used. The antenna would immediately come out if the residual charge of that device is less than 20%. As Electromagnetic (EM) waves pass into the antenna's receiving circuit, a continuous magnetic field causes a small amount of voltage. This induced voltage is not enough for charging a device. This induced voltage is multiplied four times in this amplified circuit and then connected to the battery of that device. This suggested approach would minimize charging crisis by 90%. This is one of the most efficient ways to use of renewable energy.
