Abstract:

Waveguide slot array antennas have unique qualities that make them superior to microstrip antennas in terms of loss and simpler in terms of structure than reflector antennas. As a result, they are widely employed for high-gain flat antennas in wave wireless communication systems. In order to create a slotted waveguide array or waveguide array with longitudinal shunt slots, a precise mutual coupling is necessary. SWG waveguides are used in particle trapping because of their superior bulk and surface sensitivity and their longer working distance compared to conventional nanophotonic waveguides. Furthermore, due to the requirements of basic pharmacological research and biological heterogeneity, parallel trapping of many particles is quite practicable. Furthermore, Sub Wavelength Grating (SWG) waveguides have a longer working distance, allowing for increased particle trapping and Bloch mode-induced optical forces propagation along SWG waveguides. Slotted waveguide (SWG) array has the advantage of array configuration blended with slot reduction. This work proposes two configurations of slotted waveguides excited by an energy coupled through a primary waveguide. Two array configurations with four and eight slots were simulated, successfully developed, and examined regarding the Voltage Standing Wave Ratio (VSWR), reflection coefficient,3D and 2D radiation patterns, and distant field distribution plots. The significant impact on the beamwidth (BW) is also investigated.
