Wideband microwave photonic beam steering system utilizing an array of Fibre Bragg Grating embedded in a microring


In the relatively young subject of microwave photonics (MWP), photonic technologies are used to increase microwave capabilities that are difficult to obtain directly in the microwave realm. A variety of photonic devices have been used to achieve these functionalities and provide wider beam steering without the beam squinting effect. This study investigates a microwave photonic Beam Steering System for a 2.4 GHz RF signal employing a 3X3 linear phased array antenna constructed in the S-band and operating at 2.4 GHz. As a part of the proposed design, the RF signal is guided by an optical beam-forming network with actual time delay. Multiple lengths of extremely dispersive speciality fibres are used in the optical beam forming network. The reflection properties of PS-FBGs with different bandwidths are investigated. Theoretical analysis and experimental results were used to determine the time delay response and reflectivity of PS-FBG and dispersive fibre elements. Using theoretical and pra
