“…In the previous publication [31], a curved strip dipole antenna was employed, which posed challenges in implementing a double feeding system. A modified version of the magneto-electric curved strip dipole with a Γ-shaped strip, as proposed in [32], [33], was adopted as a solution to these challenges. This modification enables efficient ±45˚ polarization feeding, as illustrated in Fig.…”

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.INDEX TERMS Circular polarization, magneto-electric antenna, metamaterials, curved strip dipole, high gain.

“…Most electric field vectors are generated at the ends of both arms, primarily because the electric field radiates based on the electric dipole principle. Additionally, the design incorporating curved dipole arms significantly contributes to wide bandwidth, high gain, and symmetric radiation patterns [31], [32], [33].…”
