Radiation Beam Width and Beam Direction Electronic Control of Transparent and Compact Vivaldi Antennas

In this paper, we present a study on broadband transparent tapered slot antenna. general, the objective of achieving optical transparency is to enable antennas seamlessly integrate into windows, offering an aesthetically pleasing and inconspicuous appearance. The aim our research develop that possess ability adjust horizontal plane beams across wide frequency range, from 24 28 GHz, for 5G applications. This structure combines three single unit, providing advantage in terms saving space. Furthermore, offers possibility choosing between using antenna obtain directional beam −90°, 0°, or +90° directions (depending activated antenna) corresponding states, combination two states another additional states. also allows acquisition state. At point, total number 23 − 1. Only PIN diodes are employed switch all Additionally, by adjusting bias values diodes, which function as variable resistors, beamwidth can be adjusted order achieve coverage 300°, more radiation pattern reconfigurability. proposed method several advantages, including simplicity feasibility controlling direction electronically. easily integrated development fifth-generation communication systems.
