Beam Steering Antenna Design with High Gain for Satellite Communication

This article presents an in-depth design of advanced beam steering inner ring structure (ABS-INS) with high gain for satellite communication systems. This design consists of a novel forty-two elements of a unit-cell compacted with the composite system. As the antennas are essential components for various applications specifically, in communication systems, therefore, several antennas have been designed for this purpose. For future generation communication systems, there is a need for beam steering antennas to solve high path loss challenges, low gain, attenuation of objects, and misalignment of antennas. We have designed an antenna array to feed on a dielectrics image line with a movable reflector plate. Moreover, unlike other reported antenna designs, which feed on image lines only, the serial beam gets more signals with coupling to dielectric image line from the waveguide with the transition to allow proper propagation and desired frequency range. The radiation beam angle steer when the propagation is remain unchanged with distance. The array’s beam direction is controlled by the change in perturbation distance in the dielectric image line and the movable plate. We have modelled the proposed antenna with the help of 3D electromagnetic Computer Simulation Technology (CST) studio suite a commercial simulator based on finite integration techniques and optimization of the structure parameters are performed with a time-domain solver of microwave studio. Further, the validation of the proposed model has been performed with the ANSYS HFSS simulator.
