Optically Reconfigurable Slotted Waveguide Antenna Array for 5G Applications

Rectangular waveguides with slots allows energy to escape from inside the waveguide. On a metallic waveguide, slots of the right size and placement are used to construct a Waveguide Slot Antenna. These slots are normally spaced out across the waveguide’s narrowest face. In 5G communication, mm-wave frequency is used to increase the transmission speed and it will also provide a large amount of spectrum to the 5G network. A reconfigurable antenna is one that can dynamically change its antenna characteristics in a reliable and adaptable way. Its design has been integrated with two Silicon Semiconductor Switches to enable Optical domain Reconfiguration. Experimental results demonstrate dual band approximately 33 GHz and 35 GHz. More numerical research revealed that the radiation pattern of the antenna had a high gain for 5G applications. For optical network-based millimetre wave applications, the developed optically reconfigurable waveguide slot antenna is essential.
