This research investigates the process of designing, practical implementation, and modification of features in a sectoral antenna for mobile communication technology. The study employs the principles of a magneto-electric dipole and metamaterials to achieve its objectives. The antenna comprises a pair of magneto-electric curved strip dipoles arranged in a cross configuration for feeding. The antenna superstructure is constructed using a metamaterial consisting of three layers of metallic rods and a U-shaped reflector plane. The feeding component is oriented orthogonally to the ground plane at angles of ±45 degrees and is powered by two crossed-shaped strips to achieve dual polarization. Circular polarization can be attained through a three-layer metamaterial, providing control over the electric field’s magnitude and phase. Additionally, the U-shaped reflector plane reflects waves, effectively increasing the sectoral antenna’s beamwidth. The sectoral antenna achieves a peak gain of 15.35 dBi, representing an improvement over the initial gain of 9.8 dBi achieved solely through the use of magneto-electric curved strip dipoles. This proposed methodology can be adapted to enable circular polarization for mobile communication. |
