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.

“…According to research, frequency diversity antennas helped lower signal correlation and prevent any potential connection issues, like in [4]. The switching ability in radiation pattern diversity can greatly enhance the connection margin while suppressing co-channel interference by directing the energy precisely toward the required direction [5]. Switched beamforming antenna array technology is a type of antenna array system that uses a simpler and less complex algorithm than other beamforming techniques, such as digital beamforming.…”

“…It can be noticed from Fig.7that when port 1 is fed, the phases ∠S(6, 5), ∠S(7,6), and ∠S(8, 7) are roughly −43.6 • at 6 GHz. The letter X in Fig.7's legend refers to the exciting port; in other words, if the first port is fed, the phase difference between ports 5 and 6 (∠S(6,5)) may be computed by subtracting the angle ∠S(6, 1) and angle ∠S(5, 1), and the other angles may be calculated in the same way. In the case that port 2 is excited, the consecutive phase difference goes to 136.96 • .…”

In this study, a novel Switched Beam Antenna (SBA) system is proposed and experimentally validated for C-band applications. The system is made up of a 4 × 4 Butler matrix, whose outputs are connected to four square-looped radiator antenna elements. The originality of the proposed work depends on the construction of a miniaturized beamforming network with minimal complexity, low loss, and low expense. Moreover, designing a system with a broad frequency range enables its use in a variety of applications. Miniaturization is achieved by eliminating the crossover and integrating the 45 • shifter into the 90 • hybrid coupler, as well as tilting the antenna array (i.e., making the Butler matrix output and the feed line of the antenna element orthogonal). The simulated results of the phase difference between the suggested Butler matrix outputs closely match the −45 • -135 • theoretical calculations. The SBA measured results show a wide bandwidth and low insertion loss of 63.64% (4.21-8.14 GHz) and −4.89 dB, respectively. Four orthogonal beams are produced by the proposed structure's input ports 1-4 when they are excited. These beams are aligned at angles of −10 • , 60 • , −60 • , and 10 • at 5.7 GHz.
