AbstractIn this paper, a cross dipole antenna is proposed, designed, and developed for satellite communication applications. The design incorporates an alternative feeding mechanism of the coaxial/probe feeding technique with balun. The primary objective of this paper is to develop the high gain antenna with an array configuration for satellite communication. The performance parameters of an antenna such as return loss, radiation pattern, gain and directivity are investigated for cross dipole antenna and 1 × 2, 1 × 4 array configurations. It operates for Ku band (12–18 GHz) and produces a high gain with low return loss.

The cross dipole antenna is analyzed for 1 × 2, 1 × 4 array configuration in order to improve the overall gain. The proposed antenna is fabricated on FR4 substrate with a dielectric constant of 4.4 and loss tangent (tan δ) of 0.007 with the thickness of 1.6 mm. The size of the proposed antenna is 72 × 84 mm. The proposed antenna meets the requirements of an antenna which is operating at Ku band; hence, it is found to be suitable for real time applications.

The emergence of new IoT applications in regional and remote areas has increased the need for a global IoT connectivity beyond existing terrestrial network coverage. However, in many cases, it is not economically viable to build a dedicated terrestrial network to cover these remote areas due to population sparsity and the lack of business case. In this paper, we propose a framework for designing a solar rectenna for IoT-over-satellite applications using nanosatellites. Utilizing such a framework will allow valuable radio spectrum resources to be shared between satellite and terrestrial users. Thus, the autonomous power supply of these objects becomes a big challenge. Indeed, the harvest of solar energy and the conversion of RF energy into electric voltage are a hot topic. Our contribution consists in offering a solar rectenna system to collect solar and RF energy as well as the radio frequency transmission. A parametric study is carried out to follow the influence on the performance of this system. A topology of rectifying circuits is proposed in the present work. The parametric study has shown that the efficiency RF/DC conversion can reach 23.2% for an input power of 5 dBm and a load resistance of 2 k Ω . To ensure the satellite communication of IoT-connected autonomous objects, this system is operated in the X or Ku band.

Genetic Algorithm (GA) is proposed in this paper for the design of a wide bandwidth, high gain and directive CPW-fed slot-dipole antenna. The proposed antenna is built on a FR4 substrate that is cheap and easy to produce. Genetic Algorithm is used to select parameters that reflect antenna geometry to achieve wider bandwidth and reduced return loss (parameter S11) and high gain values at resonant frequency. The antenna design shows a wide operating bandwidth of 1.4 GHz (simulated) and 1.3 GHz (measured) over the X-band, a return loss (S11) of -25.83 dB (simulated) and -23.08 (measured) and a gain and directivity of 5.61 dB (simulated) and 11.87 dB (simulated) at 10.5 GHz resonating frequencies. In this work, all simulations were performed using the ANSYS HFSS v14.0 software. A prototype antenna was produced and then characterized using VNA to validate the design. Measurement results were in good agreement with the results simulated using ANSYS HFSS.

Abstract In this paper, non-uniform meandered line shunt capacitive RF-MEMS switch is presented at an elliptical patch etched with a split-ring resonator (SRR) for satellite communication applications. The non-uniform meander line shunt capacitive is a fixed-fixed type of RF-MEMS switch that is introduced in this model antenna. The proposed antenna design is resonated at 10.46 GHz with the return loss of −37.6 dB. The performance evolution of the proposed antenna design is evaluated with and without integrated RF-MEMS switch on the proposed antenna SRR. It is observed that the proposed model at the ON-state switch resonates at 10.57 GHz frequency with the return loss of −30 dB. Similarly, at the OFF-state switch, it resonates at 10.53 GHz frequency with the return loss of −43 dB. Al3N4 (aluminum nitride) is used for the switch as a dielectric material, hence the switch attains higher isolation. The actuation voltage of 7.9 V is required for the switch to actuate from ON to OFF state. The switch attains minimum insertion and return loss which is discussed in further sections. The proposed antenna is fabricated and tested by a vector network analyzer; there is a good agreement between the simulated and measured results.

Abstract This study presents the design of a reconfigurable c-shaped dipole antenna for Wi-Fi and LTE bands. It consists of two nested c-shape resonators located inside each of the wings of the c-dipole patch antennas. The mentioned resonators have been used due to their inductive and capacitive effects. The reconfigurable property of the proposed antenna has been achieved with two graphene layers which are deposited on two gaps over the patch antennas.The graphene layers adjust the return loss of the proposed antenna into the desired band. These graphene layers are examined with different chemical potentials, so that the antenna return loss changes over the. The simulation results show that the gain of the antenna is higher than 5dB for both LTE and Wi-Fi applications.
